An Artic airmass will bring sharp to severe frosts with ice on footpaths and roads. Showers of hail, sleet, snow and freezing rain are likely with fog and possibly freezing fog towards the weekend.
Meteorologist Andrew Doran Sherlock explains “the most severe impacts will be on driving conditions which could be treacherous in places on Thursday morning, particularly during commute times”
Airmass chart for Thursday 8th December showing a cold (blue) airmass extending southwards over Ireland.
Very cold conditions will set in as an Arctic airmass moves southwards, extending over Ireland. Daytime temperatures will struggle to reach the low single figures. Air temperatures will widely drop to -4°C or -5°C at night, dropping down lower locally, with ground temperatures expected to fall further. A status yellow low temperature/ice warning has been issued for Thursday with further warnings likely to be required for the following days.
Wintry showers with falls of hail, sleet and snow are expected which will lead to dangerous conditions on paths and roads. Freezing rain is also possible, resulting in black ice.
Mist and fog will also be a feature of the nights and with very slack winds over the weekend, widespread and dense fog is expected, lingering in some parts through much of the day. Freezing fog is also a possibility.

Freezing Rain & Black Ice
Water droplets don’t necessarily freeze immediately when the air temperature falls below 0°C as they need freezing nuclei to convert to ice particles. Rain droplets that exist below 0°C are said to be supercooled. Freezing rain is where these supercooled water droplets fall to the surface causing significant disruption and hazardous conditions. While unusual in Ireland, freezing rain does sometimes occur, converting to black ice when it hits a surface. Black ice is especially dangerous as it is invisible and can be mistaken for wet surfaces – leading to treacherous conditions on roads and paths. Freezing rain can also lead to ice build-up on car windscreens impairing visibility.
Fog & Freezing Fog
Fog is essentially thick, low lying cloud composed of tiny water droplets (1 million fog droplets is equivalent to 1 rain droplet) suspended near the Earth’s surface where visibility is reduced below 1km. The reduced visibility is a major hazard for those travelling on or near roads. Freezing fog is where the water droplets are supercooled, and while suspended in the air, can be converted to ice upon contact with a surface such as a car windscreen. This leads to further hazardous driving conditions.
Climate Statistics
Irelands’ coldest day in December occurred on Christmas day the 25th December 2010. The air temperature at Straide, County Mayo dropped to -17.5°C and 11cm of snow was observed at this station that morning.
Although it is too early to say that 2022 will be Ireland’s warmest year on record yet, what would we need for this to be a record-breaking warm year? And will this cold spell stop Ireland having its warmest year on record?
The average daily maximum temperature we expect in Ireland in December is generally in the range of 7 to 10°C and the average daily minimum temperature we expect in December in Ireland is generally in the range of 2 to 5°C.
According to Met Eireann’s latest statistics, Ireland would have to have a December monthly mean temperature of 4.05°C or below to not have the warmest year on record.
A December monthly mean temperature of 4.05°C has only happened 7 times in 123 years, the last couple of times being Dec 2009 and 2010, when it was 4.01°C and 1.44°C respectively.

(Updated by Brandon Creagh, Meteorologist, Forecast Division, Met Éireann on Thursday 11th August 2022)
HARMONIE maximum and minimum air temperature forecast – Thursday 11th to Sunday 14th august
High pressure will generally dominate our weather over the coming days, so as it’s warming up once again, what are we to expect with this spike in temperatures?
First off, will this be a heat wave?
Well for the first time this summer we can say with a high degree of confidence that heatwave criteria will be met in some parts of the country.
So what exactly defines a heat wave?
The definition of a heat wave in Ireland is shaded air temperatures reaching highs of above 25˚ C on five or more consecutive days at the same location.
So where in Ireland is likely to see widespread temperatures with maxima in excess of 25˚ Cover the coming 5 day period?
From at least Wednesday the 10th through Sunday the 14th, maximum temperatures above 25˚ C look very likely for much of Munster and Leinster, and in large parts of these provinces, temperatures are likely to reach the upper 20’s for Friday, Saturday and possibly Sunday.
There is an exception to be made here; even though winds over land will be quite low, sea breezes will set up especially along east and south-east coasts and this will limit the maximum temperatures to the lower 20’s close to the shoreline.
Over Connacht and Ulster maximum temperatures will be mostly in the low to mid 20’s on Wednesday and Thursday, however maximum temperatures will rise to the mid 20’s or a little higher from Friday onwards, so while temperatures may rise above 25˚ C in some parts over the coming 5 days it is unlikely that at any one station this will happen on all 5 days and thus will fall short of the heatwave criteria.
Sea fog may linger locally on all coasts at times also and that will limit maximum temperatures in these locations.
Uncertainty increases as we progress through Sunday and into the early days of next week with a slight chance of thunderstorms later on Sunday and into Monday, likely heralding a return to cooler near average temperatures.
Where will be warmest and are there any high temperature warnings?
Much of Munster and Leinster will see temperatures rise into the upper 20’s later in the week, although coastal fringes will remain slightly less warm. A status yellow high temperature warning has been issued with highs likely to exceed 27 degrees over a large area for more than 2 successive days, beginning on Thursday, while night time lows will remain above 15°C for much of the night time hours over the same region. As the week progresses and the forecast becomes more certain, some counties further to the north and west like Galway and Roscommon may be added also.
Will the record for highest temperature in August be broken?
The highest August temperature was set 27 years ago on Sunday 2nd August 1995 at Oak Park, Co. Carlow (11.3°C above its 1981-2010 long-term-average), with 31.5°C.
Oak Park will likely be one station to watch again later this week, especially on Friday and Saturday, the likelihood of exceeding the August record temperature is quite low. However, temperatures exceeding 30°C locally cannot be ruled out.
Phoenix Park, Co Dublin observed at 14:40 Irish time (13:40 UTC) on Monday 18 July 2022 a shade maximum air temperature of 33.0 °C which is 12.8 °C above its 1981-1981 long-term average (LTA) of 20.2 °C.
Update by Brandon Creagh, Meteorologist, Forecast Division, Met Éireann on Thursday 11th August 2022
How is the heatwave evolving?
All areas in Ireland are now expected to become very warm or hot from tomorrow onwards, and so the Status Yellow temperature warning has been extended to all counties from 12:00 Friday until 06:00 Sunday.
Wednesday temperatures:
As Paul predicted, Oak Park in Carlow was the station to watch as it recorded the highest temperature yesterday of 29.2 degrees Celsius.
50% of stations in Met Eireann’s TUSCON station network reached 25 degrees, signalling the likely start of a heatwave, with mainly coastal stations remaining below the threshold.
Thursday temperatures:
Oak Park in Carlow is again today’s hottest station, recording 30.0°C at 1500, just below the record for August, which remains at 31.5°C for the time being.
So far today 57% of TUSCON stations have reached at least 25°C, signalling more widespread hot temperatures today.
Has the weekend forecast changed?
Very little has changed for the weekend forecast and we remain on track for this spell of hot weather to reach heatwave criteria, as daily temperature maxima will very likely remain above 25°C.
Saturday:
Sunday:
The Breakdown:
The high pressure system largely responsible for the spell of hot weather will likely break down on Sunday, with medium-range models predicting low pressure to push up from the southeast and bring possibly heavy and thundery showers on Sunday evening.
What are the major impacts and concerns for this potential heatwave?
Water safety
Unfortunately there have been a number of water related fatalities this year, and it is therefore paramount that water safety is at the forefront of our minds when it comes to enjoying the warm conditions, or seeking relief when it gets too hot.
Please follow water safety guidelines and be vigilant of those around you. Check the latest sea area and inland lakes forecasts here.
Average UV and temperatures rise and fall during the day during Summer
Hydration is once again very important through this period as it will also remain very warm and muggy at night time. This applies to farm animals and pets also.
Conservation of water and fire risk
With ground conditions becoming very dry over the course of the summer, water tables are low and water should be conserved where possible. So try and only use water where necessary and avoid wastage.
With the very dry conditions and the gradual increase in temperatures exacerbating that, fire risk will be high so always make sure to properly extinguish barbeques, and avoid lighting open fires in wooded or grassland areas.
Please remember that warm or hot spells like this actually contribute the greatest weather related risk to life, so while it can be a welcome event for some, please be cautious to the many risks to your health and safety.
For full information on government guidance to staying safe in summer, please consult the Be Summer-Ready booklet.
Over recent decades we have observed an increase in the frequency, duration and intensity of extremely hot weather across most global land regions. Human-caused climate change resulting from greenhouse gas pollution is the main driver of this increase in extreme heat.
The Phoenix Park has provisionally recorded the highest temperature since its weather station opened in the early 1800s, reaching 33.0°C on Monday 18th July 2022 around 3:30pm, which is:
8°C above its long-term average (LTA)
2nd highest temperature on record for Ireland, being 0.3°C below the all-time record of 33.3°C observed at Kilkenny Castle on Sun 26 June 1887
highest in the 21st century – beating Elphin, Co. Roscommon’s record of 32.3°C on Wednesday 19 July 2006
higher than any temperature of the 20th century, which was 32.5 °C at Boora, Co. Offaly on Tuesday 29 Jun 1976
highest temperature ever recorded in Dublin
Other stations which have recorded provisional highest-ever temperatures are Dunsany, Co. Meath at 30.2° (10.7°C above LTA), and Mullingar, Co. Westmeath at 30.4°C (11.2°C above LTA).
Europe is currently experiencing one of the hottest and driest summers on record, with widespread wildfires, excess deaths and water shortages reported in Spain, France and Portugal. The UK has issued its first ever red warning for exceptional heat as temperatures could reach 40°C in some places.
While extremely hot weather does occur within natural climate variability, the kinds of temperature extremes we are seeing in Europe are directly influenced by climate change. Keith Lambkin, Head of Met Éireann’s ‘Climate Services Division’ said “ Due to climate change, we are expecting to see heatwaves become longer, more frequent and intense than in the past. This increase in heat, increases the odds of temperature records being broken.”
Sweltering heat forecast from 17th to 19th July – what to expect
by Meteorologist Paul Downes
While Europe has been basking in what seems like an eternal heat wave all summer long, Ireland has seen mostly a very average summer. Over the next few days however a combination of factors will help to steer those higher temperatures our way, if only for a relatively brief spell of very warm temperatures.
So what is causing it?
ECMWF-Temperature and geopotential height forecast.
Initially a portion of the Azores High will extend from the southwest over Ireland for the weekend. It will bring a rise in temperatures but still hold the warmer air to the south. As the high pressure moves away to the east, the anticyclonic, or clockwise rotation will steer up air from the southeast, but the real contributing factor is how it interacts with a low pressure system developing off the coast of Portugal and gradually meandering northwards. The cyclonic or anticlockwise flow of the low working in conjuction with the anticyclonic flow from the high will generate a strong surge of warm air between both systems thus pushing the warm air towards Ireland, transporting the airmass that has brought exceptional temperatures to Europe, towards Ireland.
What temperatures should we expect?
While the high builds in on Friday and Saturday the high temperatures will range generally in the low to mid 20’s. There will also be some upper cloud at times making sunshine a little hazy and there is a chance of a few showers too.
As the high begins to drift a little to the east on Sunday, temperatures will rise to mid to upper 20’s with temperatures possibly surpassing 30 locally on Monday. There is a little more uncertainty regarding Tuesday but it does look like it will be another hot day and perhaps as hot if not hotter than Monday. While this warmer air moves in our direction there will be the chance of a few thundery bursts especially on Tuesday.
Maximum temperatures Saturday to Sunday – ECMWF
Maximum temperatures Sunday to Monday – ECMWF
Maximum temperatures Monday to Tuesday – ECMWF
Maximum temperatures Tuesday to Wednesday – ECMWF
With temperatures soaring, it is important to remain hydrated and be Sun Smart, that goes for animals as well as ourselves. Be prepared and remember to Be Summer Ready
The night time temperature will also be very warm and humid with temperatures on Sunday and Monday night not likely to fall below the mid to high teens and in some areas they may not fall below 20°C, which is known as a Tropical night.
Status Yellow High Temperature Warning Issued
We have issued a Status Yellow High Temperature warning for Ireland.
On Sunday, Monday and Tuesday exceptionally warm weather will occur over Ireland with daytime temperatures of 25 to 30 degrees generally and possibly up to 32 degrees in places on Monday. Night time temperatures will range from 15 to 20 degrees.
Impacts:
• Heat stress, especially for the more vulnerable of the population
• High Solar UV index
• Risk of water related incidents
Currently it looks as if the breakdown will happen on Tuesday night into Wednesday as the Low pressure system moves up over Ireland steering in cooler air from the west for the rest of the week. This will also bring some wet conditions on Wednesday.
Climate Change & Extreme Heat – July 2022
Over recent decades we have observed an increase in the frequency, duration and intensity of extremely hot weather across most global land regions. Human-caused climate change resulting from greenhouse gas pollution is the main driver of this increase in extreme heat.
The Phoenix Park has provisionally recorded the highest temperature since its weather station opened in 1891, reaching 33.0°C on Monday 18th July 2022 around 3:30pm, which is:
12.8°C above its long-term average (LTA)
2nd highest temperature on record for Ireland, being 0.3°C below the all-time record of 33.3°C observed at Kilkenny Castle on Sun 26 June 1887
highest in the 21st century – beating Elphin, Co. Roscommon’s record of 32.3°C on Wednesday 19 July 2006
higher than any temperature of the 20th century, which was 32.5 °C at Boora, Co. Offaly on Tuesday 29 Jun 1976
highest temperature ever recorded in Dublin
Other stations which have recorded provisional highest-ever temperatures are Dunsany, Co. Meath at 30.2° (10.7°C above LTA), and Mullingar, Co. Westmeath at 30.4°C (11.2°C above LTA).
Europe is currently experiencing one of the hottest and driest summers on record, with widespread wildfires, excess deaths and water shortages reported in Spain, France and Portugal. The UK has issued its first ever red warning for exceptional heat as temperatures could reach 40°C in some places.
While extremely hot weather does occur within natural climate variability, the kinds of temperature extremes we are seeing in Europe are directly influenced by climate change. Keith Lambkin, Head of Met Éireann’s ‘Climate Services Division’ said “ Due to climate change, we are expecting to see heatwaves become longer, more frequent and intense than in the past. This increase in heat, increases the odds of temperature records being broken.”
What brought the heat to the south-western part of the continent?
High pressure ridge already formed in the South West Europe by 12 June 2022, with an Atlantic low-pressure system between the Azores islands and Madeira, which caused the uprising of warm air in western Europe (source: WMO). This ridge did not move and the temperatures rose gradually day to day. Maximum temperatures were often above 30°C and 8 to 10°C higher than the climatological average.
WMO Tweet
Provisional temperature records
Saint-Jean-De-Minervois reached 40°C on 16 June, earliest every 40°C in France. Cottbus, Germany temperature 140 year-old record was broken with 39.2°C on 19 June 2022 (since 1888, previous record was 38.9°C set on 29 July 1921). Up to 43°C was observed in Andalusia, Spain. A June temperature record was broken for the western part of Austria with 36.5°C. High temperature records were also set in Czech Republic, Poland and Switzerland.
The heatwave is expected to come to the rest of central and south Europe in the next few days. While a Saharan dust storm will deteriorate air quality in southern France, Italy, Balearic Islands, Spain & the Balkan Peninsula. (source: CopernicusEU) .
“Climate projection models suggest that heatwaves as likely to become more frequent, longer and more intense, start earlier and finish later than in the past.” Keith Lambkin, Senior Climatologist.
Why did Ireland not achieve these high temperatures?
On Saturday, a front lay over the southeast of the country which slowly cleared south-eastwards. A moderate northwest breeze which felt cool and kept the temperatures low. On Sunday, there was a depression of 999 hPa centred to the northwest of Scotland which was tracking eastward. So the air across Ireland is flowing eastward, keeping the continental heat away from our shores.
What is a climatological heatwave in Ireland?
In terms of climate monitoring, a heatwave occurs at a station when there five (5) consecutive days or more observe a daily maximum temperature over 25 degrees Celsius (> 25 °C).
In general in Ireland, heatwaves occur in June, July and August. There has been only one instance of a heatwave beginning in May (Glenties Hatchery, Co Donegal in 2012) and four starting in September, all within the first 2 weeks – one occurring in 1959 and the others occurred in 1991. The peak month for heatwaves in Ireland is July. The average heatwaves is 6 days long. It would be rare to have a heatwave longer than 9 days. The longest heatwave observed is 14 days in Laois and Offaly in August 1976.
Temperatures in June 2022 so far
The highest daily maximum shaded air temperature of 2022 so far is 23.9°C which occurred on Thursday 16 June 2022 at Phoenix Park, Co Dublin.
Currently June 2022 is two thirds completed and is 41st warmest June on record (Island of Ireland long-term series, 123 years) with an average temperature to yesterday of 13.7°C. This value is a half degree above June’s 20th century average (1901-2000) and is currently on average to the 1991-2020 June average. Typically in Ireland, we would expect warmer temperatures towards the end of the month, as the summer progresses. So we are expecting June 2022 to be warmer than 41st warmest. We will have to wait another 10 days to find out however.
The warmest June occurred 82 years ago in 1940 with 15.4°C.
The coldest June occurred 50 years ago in 1972 with 11.1°C.
Of the ten warmest Junes on record, half have occurred from 2005 onwards. Of the 41 warmest Junes, just over a third have occurred from 2003 onwards.
No Junes in the 21st century (2001-2022) appear in the coldest ten Junes. Of the 41 coldest Junes, only 5% have occurred from 2011 onwards.

What’s in store for the coming days of June 2022
Keep up to date with the latest forecasts and warnings:
May 2022 was provisionally Ireland’s 3rd warmest on record. The average temperature being 12.6°C, which is 1.9°C above May’s 20th century average (1901-2000) and 1.3°C above the 1991-2020 average.
Across Europe, temperatures in May 2022 varied considerably compared against the average May values for 1991-2020. The Sahara influence again meant hotter than average in the far west of Europe. While many countries, France, Spain and Portugal broke records.
Globally, May was the fifth warmest on record, joint with May 2018 and 2021.
Following the current spell of warm and dry weather it’s going to turn much colder by mid-week as a cooler airmass arrives across Ireland from Scandinavia.
The highest temperature of 2022 so far was recorded on Sunday, with 18.9 degrees reached at Newport Furnace, Co. Mayo. While the pleasant weather will continue on Monday and Tuesday, there is the chance of a few showers at times mainly over the eastern half of the country, generated by more unstable air. However the most significant change will come on Wednesday as a northerly airflow establishes across the country feeding in noticeably colder air from Scandinavia.
Met Eireann meteorologist, Brandon Creagh, said: “It’s going to get noticeably colder from Wednesday as an anticyclone over Iceland will bring cold northerly winds over Ireland on Wednesday and into Thursday. Showers will develop over the eastern half of the country with a slight risk of wintry precipitation over high ground.”
Airmass chart for Thursday 31st March showing a cold (blue) northerly airmass over Ireland, originating from Scandinavia.
The colder spell may come as a bit of a surprise to some as temperatures over the last week have been well into the mid to high teens – above average for the time of year, however from Wednesday we’ll see daytime temperatures drop back down into single figures.
Meteorologist Brandon Creagh added: “It’ll be important to bring plants indoors that are sensitive to cold. Also, farmers and gardeners should be aware that growing conditions will not be as good as they have been recently.”

High pressure over Europe will become centred over Ireland in the coming days, bringing a good deal of dry and mild weather along with plenty of sunshine.
Met Éireann meteorologist, Aoife Kealy said: “The dry and bright weather that we’ve had over the past few days won’t be going anywhere this week. High pressure is going to stay very firmly in charge so we can generally expect plenty of sunshine and little or no rain.”
“Some very weak fronts will drift into western and northern areas later this week so it’ll be a bit cloudier there at times with a few spots of drizzle but any accumulations will be small. So, even though it won’t be wall-to-wall sunshine, it will be very pleasant still.”
Daytime temperatures will be on the mild side for March and at night temperatures will drop into the low single figures, so a few patches of grass frost are still possible, especially when the skies are clear.
Aoife continued: “It’s the daytime temperatures that are notable though. The average maximum temperatures for this time of year are around 11 or 12 degrees, but the combination of a relatively mild airmass and good spells of sunshine mean that top temperatures this week will widely get into the mid-teens, even hitting the high teens at times.”
This current spell of settled weather looks to last into at least this weekend. Aoife explained: “Although there’s a bit of uncertainty later this weekend, there’s no real sign of this high pressure breaking down until early next week at least. So, this really lovely spell of spring weather won’t be going anywhere too quickly.”
UV and Pollen forecasts for 2022 begin this week
With spring in full force and plenty of sunshine across the country this week, pollen and UV levels will start to increase. You can now find the latest UV and pollen forecasts for 3 days ahead on the Met Éireann website and app.
For more information on staying safe in the sun please visit our UV Index page.
After a changeable week, our weather will remain mixed as we head into the weekend with the potential for heavy rain in some places but also some drier and brighter weather too.
Met Éireann Meteorologist Emer Flood said: “An active jet stream will continue to steer Atlantic low-pressure systems in our direction over the coming days, these will bring spells of heavy rain and strong winds at times.
“Heavy rain will move into the southwest on Thursday night, becoming widespread Friday morning which may lead to localised surface flooding. There is also potential for further heavy rain and strong winds over the weekend with the possibility of warnings being issued. We’re advising everyone to keep a close eye on the forecast for the coming days.”
A yellow rain warning is in place for many southern and western counties from 15:00 on Saturday afternoon until around midnight, where heavy rain along with strong winds will bring a risk of flooding and hazardous driving conditions.
On Friday, rain will be quite widespread and heavy in places, slowly clearing northeastwards in the afternoon. This will be followed by heavy showers with the potential for thunderstorms and hail, which could lead to some localised flooding and hazardous driving conditions.
Some heavy or prolonged showers will continue overnight Friday into Saturday morning. Otherwise, Saturday will start off dry and bright in many areas. However later in the day a low-pressure system will approach from the southwest, with cloud building and winds strengthening as rain arrives across the southern half of the country by evening. Rain may turn to sleet or snow in parts, especially over high ground. Sunday will be wet and windy for many as this same low-pressure system slowly pushes north over Ireland with further falls of sleet or snow possible locally.
Looking ahead to next week there are signs of a quieter and more settled spell on Monday and Tuesday, though this may be short-lived as things once again turn more unsettled around midweek.

A brief cold snap on the way on Wednesday evening and Thursday, with wintry showers of hail, sleet and snow along with strong and gusty winds leading to some impacts in areas.
A cold front moving across Ireland this afternoon (Wednesday 23rd) will introduce a much colder and unstable polar maritime airmass tonight and tomorrow. Met Éireann has issued several yellow weather warnings including yellow level snow/ice and wind warnings. These warnings are in place for many northern and western counties for tonight and Thursday.
Staying unsettled & turning cold over the next few days with wintry showers on Wednesday night & Thursday.
Some snow is likely in places & showers will be heavy with possible hail & thunder too.
Met Éireann meteorologist Emer Flood said, “Temperatures will drop quite quickly this evening with the chance of frost and ice forming, especially for inland and rural areas.
“It’ll be windy tonight too especially in northern and western areas, this helping to drive wintry showers of snow, sleet and hail inland. Some areas especially in the northwest will see some snow accumulations of a few centimetres to lower levels, accumulations elsewhere will be mainly confined to high ground.
“It’ll remain very cold and windy across the country on Thursday with continued snow showers, this leading to treacherous driving conditions from icy stretches and reduced visibility on the roads in places. This polar maritime airmass is quite unstable so we could see some hail and lightning at times throughout Thursday too.”
Temperatures on Thursday will be limited to around 3 to 7 degrees, with the brisk northwesterly winds making it feel much colder.
Commenting on the forecast for the rest of the week, Emer continued: “Following this cold spell, temperatures will recover on Friday and into the weekend with highs of around 8 to 10 degrees. Although there is some rain in the forecast over the weekend, much of this will fall overnight so there’ll be decent spell of dry and bright weather around over the weekend too.”

After what’s been a fairly settled February so far, our weather will turn increasingly unsettled over the weekend with some wet weather on the way on Sunday and early next week.
Met Éireann have issued yellow wind warnings for Donegal, Galway and Mayo and rain warnings for Cork, Kerry and Galway on Friday afternoon and Saturday morning, due to spells of heavy rain and strong winds to mainly southern and western areas. It’ll stay breezy across the country on Saturday with some blustery, heavy showers, followed by a rather wet day across the country on Sunday.
Met Éireann meteorologist, Mark Bowe, said:
“Our weather has been pretty settled so far this year thanks to high pressure never being too far away. But as we head into the weekend and next week we’re going to see a change to more unsettled weather as the jet stream positions itself across Ireland – this will open the door to low pressure systems moving in from the Atlantic.”
“We’re keeping a close eye on the weather forecast for Sunday, as a low pressure will swing up from the south bringing outbreaks of rain through the day. There is likely to be some heavy bursts of rain in places which could lead to some localised flooding, but there’s still quite a bit of uncertainty so it’s best to keep an eye on the latest forecast and warnings, especially if you have plans this weekend.”
Currently ground conditions are either waterlogged or saturated and further rainfall over the weekend and next week will add to water levels, with the possibility of some localised flooding. You can find out more about current ground conditions here https://www.met.ie/forecasts/farming#agri-graphs.
Mark continued: “With further low-pressure systems moving our way early next week there is the potential for further spells of wet and windy weather. We’re keeping a close eye on Tuesday in particular as there are signs of heavy rain in the forecast. With ground levels already waterlogged this could lead to some localised impacts from flooding, so stay keep an eye on the latest forecast and warnings from Met Éireann for your area.”

Tar éis maidin scamallach den chuid is mó agus roinnt báisteach éadrom ag fanacht i gcodanna, beidh an tráthnóna tirim den chuid is mó le geasa geala. Beidh sé an-éadrom, le teocht tráthnóna 11 go 14 céim.
Rachaidh an ghaoth in olcas go dtí an ghaoth measartha fearúil tráthnóna Dé hAoine, ach beidh an tréimhse níos ciúine seo gearr go leor mar beidh na gaotha ag neartú arís níos déanaí sa tráthnóna ar Oíche Chinn Bhliana. Méadóidh gaotha an deiscirt ó úr go láidir go luath san oíche, leis na gaotha is láidre ar chóstaí an Atlantaigh. Beidh sé fliuch in áiteanna freisin agus ráigeanna báistí ag bogadh soir thar oíche. Fanacht éadrom thar oíche le teocht is ísle de 9 go 11 céim.
Beidh an aimsir don chéad lá de 2022, Dé Sathairn, an-bhrónach le cithfholcadáin, cuid acu sin trom. Beidh tréimhsí geala agus grianmhara ann freisin, áfach. Beidh sé grianmhar le gaotha an iardheiscirt úr, is gaofar in aice le cóstaí an iarthair agus gaotha fós láidir ann. Leanfaidh sé níos séimhe ná an meán, agus beidh an teocht is airde de 11 go 13 céim.

Leanfaidh brú ard orainn ag coinneáil ár n-aimsire socraithe agus tirim den chuid is mó tríd an deireadh seachtaine seo agus isteach i laethanta tosaigh Sheachtain na Nollag, cé go bhfuil roinnt comharthaí ann go mbeidh aimsir níos neamhshocraithe ann ó lár na seachtaine ar aghaidh agus b’fhéidir ag éirí níos fuaire thar dheireadh seachtaine na Nollag.
Dúirt meitéareolaí Met Éireann, Deirdre Lowe: “Bainfidh an chuid is mó againn sult as aimsir thirim chiúin roimh an Nollaig, beidh sé measartha scamallach agus feicfidh roinnt spotaí ceo beag fánach nó ceochán i scamall níos doimhne. Rachaidh sé beagán níos fuaire i rith an deireadh seachtaine freisin, agus teocht an lae idir 6 agus 9 Celsius.”
“Fanfaidh sé measartha scamallach i rith na n-oícheanta agus ba cheart go gcoinneodh sé an sioc, cé nach féidir a chur as an áireamh an paiste corr sioc nuair a fhorbraíonn spéartha níos soiléire.”
Leanfaidh an aimsir shocraithe seo ar aghaidh go laethanta tosaigh na seachtaine seo chugainn, cé go bhfuil an chosúlacht ar an scéal go laghdóidh an brú ard de réir a chéile ó thart ar lár na seachtaine ar aghaidh, rud a fhágfaidh go mbeidh ár n-aimsir níos suaite agus muid ag druidim le Lá Nollag. Cé go bhfuil roinnt mhaith éiginnteachta sa réamhaisnéis, tá roinnt comharthaí ann go mbeidh aer níos fuaire á tharraingt ar fud na tíre thar dheireadh seachtaine na Nollag.
Lean an meitéareolaí Deirdre Lowe ar aghaidh: “Tá sé ró-luath fós a rá le cinnteacht cén aimsir ar féidir linn a bheith ag súil leis ar Lá Nollag. Faoi láthair tá an chuma air go gcuirfear brú íseal in ionad an ardbhrú blocála atá ann faoi láthair, rud a mhéadóidh an seans go mbeidh aimsir neamhshocraithe. Tá roinnt comharthaí luatha ann freisin go bhféadfadh tréimhse fuar a bheith ann thar thréimhse na Nollag ach tá sé fíorchinnte fós, mar sin coinnigh súil ar réamhaisnéis Met Éireann is déanaí.”

Mar gheall ar dhúlagar domhain an Atlantaigh beidh aimsir an-fhliuch agus an-ghaofar ar fud na hÉireann go dtí Dé Máirt agus Dé Céadaoin. Beidh gaoth láidir i ngach ceantar uaireanta agus tiocfaidh gála i gceantair cois cósta. Is dócha go mbeidh séideáin thromchúiseacha ann. I láthair na huaire táthar ag súil go mbeidh na gaotha is láidre i gcontaetha cósta thiar na Mumhan le gaotha stoirme indéanta uaireanta níos déanaí Dé Máirt.
In éineacht leis na gaotha neartaithe beidh seal de bháisteach throm ar an Máirt, agus cithfholcadáin troma ina dhiaidh oíche Dé Máirt agus Dé Céadaoin. D’fhéadfadh cuid de na cithfholcadáin a bheith ina sleá nó sneachta ar thalamh ard.
Mar gheall ar thaoidí earraigh, tonnta an-ard agus leibhéil borrtha móra, d’fhéadfadh tuilte cósta tarlú feadh chóstaí na Mumhan agus dheisceart Chonnacht.
Tionchair Féideartha
Is dócha go gcuirfidh gaotha an-láidir agus séideáin dhíobhálacha isteach ar bhriseadh cumhachta, crainn tite nó craobhacha nó smionagar eile.
Chomh maith le tuilte cois cósta, tabharfaidh báisteach throm nó cithfholcadh tuilte áitiúla. Is dócha go gcuirfear isteach ar thaisteal uaireanta mar gheall ar ghaotha láidre, droch-infheictheacht, tuilte áitiúla agus drochchoinníollacha dromchla de bharr clocha sneachta, sneachta nó sneachta ar thalamh ard.
Réamhaisnéis mhionsonraithe
Forbróidh dúlagar stoirme i lár an Atlantaigh Dé Luain mar thoradh ar bhrú dinimiciúil ón Jetstream san atmaisféar uachtarach. Doimhneoidh an córas ísealbhrú go tapa agus é ag dul soir ó thuaidh thar an Atlantach agus ag druidim le hÉirinn ar Scairdsruth láidir siar.
De réir mar a bheidh an dúlagar ag druidim le hÉirinn, tiocfaidh moilliú air agus éireoidh sé measartha mall ag gluaiseacht tríd an Máirt agus an Chéadaoin. Níl rian cruinn agus uainiú an dúlagar cinnte. Faoi láthair táthar ag súil go sroichfidh sé íosbhrú de 952 hPa tráthnóna Dé Máirt ag timpeall 100 muirmhíle nó 185 Km in iarthar na hÉireann. Líonfaidh an dúlagar go mall agus méadóidh a bhrú lárnach de réir a chéile agus é ag bogadh go mall soir thar Éirinn trí oíche Dé Máirt agus Dé Céadaoin, ag glanadh soir ó dheas trí oíche Dé Céadaoin ar deireadh.
Tá forbairt agus rian an dúlagar tríd an Luan, Dé Máirt agus Dé Céadaoin le feiceáil sna cairteacha thíos.
Réamhaisnéis na Gaoithe
De réir mar a bheidh an dúlagar ag druidim le hÉirinn, neartóidh na gaotha ó dheas trí oíche Dé Luain agus go luath Dé Máirt le gálaí nó gálaí láidre ag forbairt feadh chóstaí uile na hÉireann agus Mhuir Éireann. Forbróidh gaotha athraitheacha cioclónacha de réir mar a ghluaiseann an dúlagar ar fud na hÉireann. Níos déanaí Dé Máirt agus trí oíche Dé Máirt, forbróidh gaotha an-láidir an iarthair i gcontaetha chósta an iarthair. Tá an chuma ar an scéal faoi láthair go dtarlóidh na gaotha is láidre i gcontaetha cósta thiar na Mumhan agus Co. na Gaillimhe.

Réamhaisnéis Báistí
Níl cinnte cén t-am a thiteann báistí ar fud na hÉireann a bhaineann le dúlagar an Atlantaigh. Léiríonn an tsamhail reatha tuartha go dtiocfaidh báisteach throm in iarthar na hÉireann níos déanaí oíche Dé Luain agus go bogfaidh sé soir ar fud na tíre maidin Dé Máirt. Leanfaidh cithfholcadáin ón iarthar tráthnóna Dé Máirt agus leanfaidh siad ar aghaidh go dtí oíche Dé Máirt agus Dé Céadaoin. Beidh cuid acu geimhridh, ag titim mar chlocha nó sneachta le sneachta ar thalamh ard. D’fhéadfadh stoirmeacha toirní iargúlta a bheith ann freisin.
Coinníollacha Cósta
Táimid i dtréimhse de Thaoidí Earraigh, agus táthar ag súil go n-ardófar leibhéil chósta Dé Máirt agus córas domhainbhrúite ag druidim ón Atlantach as a dtiocfaidh gaotha láidre, tonnta arda agus leibhéil mhóra borrtha. Táthar ag súil leis na leibhéil borrtha is mó ar chóstaí an Atlantaigh. Tá éiginnteacht fós ann idir ritheanna samhlacha ar uainiú agus cosán an chórais ísealbhrú, a imreoidh tionchar ar an leibhéal borrtha a bhfuiltear ag súil leis go háitiúil feadh an chósta, agus ba cheart go laghdódh an neamhchinnteacht de réir mar a thagann rití samhlacha amach anseo ar fáil.

Tráchtaireacht an Réamhaisnéiseora
Cold Spell for the rest of this week – 6th December 2022
An Artic airmass will bring sharp to severe frosts with ice on footpaths and roads. Showers of hail, sleet, snow and freezing rain are likely with fog and possibly freezing fog towards the weekend.
Meteorologist Andrew Doran Sherlock explains “the most severe impacts will be on driving conditions which could be treacherous in places on Thursday morning, particularly during commute times”
Airmass chart for Thursday 8th December showing a cold (blue) airmass extending southwards over Ireland.
Very cold conditions will set in as an Arctic airmass moves southwards, extending over Ireland. Daytime temperatures will struggle to reach the low single figures. Air temperatures will widely drop to -4°C or -5°C at night, dropping down lower locally, with ground temperatures expected to fall further. A status yellow low temperature/ice warning has been issued for Thursday with further warnings likely to be required for the following days.
Wintry showers with falls of hail, sleet and snow are expected which will lead to dangerous conditions on paths and roads. Freezing rain is also possible, resulting in black ice.
Mist and fog will also be a feature of the nights and with very slack winds over the weekend, widespread and dense fog is expected, lingering in some parts through much of the day. Freezing fog is also a possibility.

For information on winter weather preparation, please consult www.winterready.ie
Freezing Rain & Black Ice
Water droplets don’t necessarily freeze immediately when the air temperature falls below 0°C as they need freezing nuclei to convert to ice particles. Rain droplets that exist below 0°C are said to be supercooled. Freezing rain is where these supercooled water droplets fall to the surface causing significant disruption and hazardous conditions. While unusual in Ireland, freezing rain does sometimes occur, converting to black ice when it hits a surface. Black ice is especially dangerous as it is invisible and can be mistaken for wet surfaces – leading to treacherous conditions on roads and paths. Freezing rain can also lead to ice build-up on car windscreens impairing visibility.
Fog & Freezing Fog
Fog is essentially thick, low lying cloud composed of tiny water droplets (1 million fog droplets is equivalent to 1 rain droplet) suspended near the Earth’s surface where visibility is reduced below 1km. The reduced visibility is a major hazard for those travelling on or near roads. Freezing fog is where the water droplets are supercooled, and while suspended in the air, can be converted to ice upon contact with a surface such as a car windscreen. This leads to further hazardous driving conditions.
Climate Statistics
Irelands’ coldest day in December occurred on Christmas day the 25th December 2010. The air temperature at Straide, County Mayo dropped to -17.5°C and 11cm of snow was observed at this station that morning.
Although it is too early to say that 2022 will be Ireland’s warmest year on record yet, what would we need for this to be a record-breaking warm year? And will this cold spell stop Ireland having its warmest year on record?
The average daily maximum temperature we expect in Ireland in December is generally in the range of 7 to 10°C and the average daily minimum temperature we expect in December in Ireland is generally in the range of 2 to 5°C.
According to Met Eireann’s latest statistics, Ireland would have to have a December monthly mean temperature of 4.05°C or below to not have the warmest year on record.
A December monthly mean temperature of 4.05°C has only happened 7 times in 123 years, the last couple of times being Dec 2009 and 2010, when it was 4.01°C and 1.44°C respectively.

Heatwave conditions very likely this week - August 2022
by Paul Downes, Meteorologist, Forecast Division, Met Éireann. Issued 9th August 2022
(Updated by Brandon Creagh, Meteorologist, Forecast Division, Met Éireann on Thursday 11th August 2022)
HARMONIE maximum and minimum air temperature forecast – Thursday 11th to Sunday 14th august
High pressure will generally dominate our weather over the coming days, so as it’s warming up once again, what are we to expect with this spike in temperatures?
First off, will this be a heat wave?
Well for the first time this summer we can say with a high degree of confidence that heatwave criteria will be met in some parts of the country.
So what exactly defines a heat wave?
The definition of a heat wave in Ireland is shaded air temperatures reaching highs of above 25˚ C on five or more consecutive days at the same location.
So where in Ireland is likely to see widespread temperatures with maxima in excess of 25˚ C over the coming 5 day period?
From at least Wednesday the 10th through Sunday the 14th, maximum temperatures above 25˚ C look very likely for much of Munster and Leinster, and in large parts of these provinces, temperatures are likely to reach the upper 20’s for Friday, Saturday and possibly Sunday.
There is an exception to be made here; even though winds over land will be quite low, sea breezes will set up especially along east and south-east coasts and this will limit the maximum temperatures to the lower 20’s close to the shoreline.
Over Connacht and Ulster maximum temperatures will be mostly in the low to mid 20’s on Wednesday and Thursday, however maximum temperatures will rise to the mid 20’s or a little higher from Friday onwards, so while temperatures may rise above 25˚ C in some parts over the coming 5 days it is unlikely that at any one station this will happen on all 5 days and thus will fall short of the heatwave criteria.
Sea fog may linger locally on all coasts at times also and that will limit maximum temperatures in these locations.
Uncertainty increases as we progress through Sunday and into the early days of next week with a slight chance of thunderstorms later on Sunday and into Monday, likely heralding a return to cooler near average temperatures.
Where will be warmest and are there any high temperature warnings?
Much of Munster and Leinster will see temperatures rise into the upper 20’s later in the week, although coastal fringes will remain slightly less warm. A status yellow high temperature warning has been issued with highs likely to exceed 27 degrees over a large area for more than 2 successive days, beginning on Thursday, while night time lows will remain above 15°C for much of the night time hours over the same region. As the week progresses and the forecast becomes more certain, some counties further to the north and west like Galway and Roscommon may be added also.
Will the record for highest temperature in August be broken?
The highest August temperature was set 27 years ago on Sunday 2nd August 1995 at Oak Park, Co. Carlow (11.3°C above its 1981-2010 long-term-average), with 31.5°C.
Oak Park will likely be one station to watch again later this week, especially on Friday and Saturday, the likelihood of exceeding the August record temperature is quite low. However, temperatures exceeding 30°C locally cannot be ruled out.
Weather extreme records for Ireland
What’s the highest temperature of 2022 so far?
Phoenix Park, Co Dublin observed at 14:40 Irish time (13:40 UTC) on Monday 18 July 2022 a shade maximum air temperature of 33.0 °C which is 12.8 °C above its 1981-1981 long-term average (LTA) of 20.2 °C.
Update by Brandon Creagh, Meteorologist, Forecast Division, Met Éireann on Thursday 11th August 2022
How is the heatwave evolving?
All areas in Ireland are now expected to become very warm or hot from tomorrow onwards, and so the Status Yellow temperature warning has been extended to all counties from 12:00 Friday until 06:00 Sunday.
Wednesday temperatures:
As Paul predicted, Oak Park in Carlow was the station to watch as it recorded the highest temperature yesterday of 29.2 degrees Celsius.
50% of stations in Met Eireann’s TUSCON station network reached 25 degrees, signalling the likely start of a heatwave, with mainly coastal stations remaining below the threshold.
Thursday temperatures:
Oak Park in Carlow is again today’s hottest station, recording 30.0°C at 1500, just below the record for August, which remains at 31.5°C for the time being.
So far today 57% of TUSCON stations have reached at least 25°C, signalling more widespread hot temperatures today.
Has the weekend forecast changed?
Very little has changed for the weekend forecast and we remain on track for this spell of hot weather to reach heatwave criteria, as daily temperature maxima will very likely remain above 25°C.
Saturday:
Sunday:
The Breakdown:
The high pressure system largely responsible for the spell of hot weather will likely break down on Sunday, with medium-range models predicting low pressure to push up from the southeast and bring possibly heavy and thundery showers on Sunday evening.
What are the major impacts and concerns for this potential heatwave?
Unfortunately there have been a number of water related fatalities this year, and it is therefore paramount that water safety is at the forefront of our minds when it comes to enjoying the warm conditions, or seeking relief when it gets too hot.
Please follow water safety guidelines and be vigilant of those around you. Check the latest sea area and inland lakes forecasts here.

Hydration is once again very important through this period as it will also remain very warm and muggy at night time. This applies to farm animals and pets also.
With ground conditions becoming very dry over the course of the summer, water tables are low and water should be conserved where possible. So try and only use water where necessary and avoid wastage.
With the very dry conditions and the gradual increase in temperatures exacerbating that, fire risk will be high so always make sure to properly extinguish barbeques, and avoid lighting open fires in wooded or grassland areas.

Please remember that warm or hot spells like this actually contribute the greatest weather related risk to life, so while it can be a welcome event for some, please be cautious to the many risks to your health and safety.

With some sweltering heat on the way, what is causing it and what can you expect?
**Update 1600 Monday**
Climate Change & Extreme Heat – July 2022
Over recent decades we have observed an increase in the frequency, duration and intensity of extremely hot weather across most global land regions. Human-caused climate change resulting from greenhouse gas pollution is the main driver of this increase in extreme heat.
The Phoenix Park has provisionally recorded the highest temperature since its weather station opened in the early 1800s, reaching 33.0°C on Monday 18th July 2022 around 3:30pm, which is:
Other stations which have recorded provisional highest-ever temperatures are Dunsany, Co. Meath at 30.2° (10.7°C above LTA), and Mullingar, Co. Westmeath at 30.4°C (11.2°C above LTA).
Europe is currently experiencing one of the hottest and driest summers on record, with widespread wildfires, excess deaths and water shortages reported in Spain, France and Portugal. The UK has issued its first ever red warning for exceptional heat as temperatures could reach 40°C in some places.
While extremely hot weather does occur within natural climate variability, the kinds of temperature extremes we are seeing in Europe are directly influenced by climate change. Keith Lambkin, Head of Met Éireann’s ‘Climate Services Division’ said “ Due to climate change, we are expecting to see heatwaves become longer, more frequent and intense than in the past. This increase in heat, increases the odds of temperature records being broken.”
Sweltering heat forecast from 17th to 19th July – what to expect
by Meteorologist Paul Downes
While Europe has been basking in what seems like an eternal heat wave all summer long, Ireland has seen mostly a very average summer. Over the next few days however a combination of factors will help to steer those higher temperatures our way, if only for a relatively brief spell of very warm temperatures.
So what is causing it?
ECMWF-Temperature and geopotential height forecast.
Initially a portion of the Azores High will extend from the southwest over Ireland for the weekend. It will bring a rise in temperatures but still hold the warmer air to the south. As the high pressure moves away to the east, the anticyclonic, or clockwise rotation will steer up air from the southeast, but the real contributing factor is how it interacts with a low pressure system developing off the coast of Portugal and gradually meandering northwards. The cyclonic or anticlockwise flow of the low working in conjuction with the anticyclonic flow from the high will generate a strong surge of warm air between both systems thus pushing the warm air towards Ireland, transporting the airmass that has brought exceptional temperatures to Europe, towards Ireland.
What temperatures should we expect?
While the high builds in on Friday and Saturday the high temperatures will range generally in the low to mid 20’s. There will also be some upper cloud at times making sunshine a little hazy and there is a chance of a few showers too.
As the high begins to drift a little to the east on Sunday, temperatures will rise to mid to upper 20’s with temperatures possibly surpassing 30 locally on Monday. There is a little more uncertainty regarding Tuesday but it does look like it will be another hot day and perhaps as hot if not hotter than Monday. While this warmer air moves in our direction there will be the chance of a few thundery bursts especially on Tuesday.

Maximum temperatures Monday to Tuesday – ECMWF
Maximum temperatures Tuesday to Wednesday – ECMWF
With temperatures soaring, it is important to remain hydrated and be Sun Smart, that goes for animals as well as ourselves. Be prepared and remember to Be Summer Ready
The night time temperature will also be very warm and humid with temperatures on Sunday and Monday night not likely to fall below the mid to high teens and in some areas they may not fall below 20°C, which is known as a Tropical night.
Status Yellow High Temperature Warning Issued
We have issued a Status Yellow High Temperature warning for Ireland.
On Sunday, Monday and Tuesday exceptionally warm weather will occur over Ireland with daytime temperatures of 25 to 30 degrees generally and possibly up to 32 degrees in places on Monday. Night time temperatures will range from 15 to 20 degrees.
Impacts:
• Heat stress, especially for the more vulnerable of the population
• High Solar UV index
• Risk of water related incidents

The Breakdown
Currently it looks as if the breakdown will happen on Tuesday night into Wednesday as the Low pressure system moves up over Ireland steering in cooler air from the west for the rest of the week. This will also bring some wet conditions on Wednesday.
Climate Change & Extreme Heat – July 2022
Over recent decades we have observed an increase in the frequency, duration and intensity of extremely hot weather across most global land regions. Human-caused climate change resulting from greenhouse gas pollution is the main driver of this increase in extreme heat.
The Phoenix Park has provisionally recorded the highest temperature since its weather station opened in 1891, reaching 33.0°C on Monday 18th July 2022 around 3:30pm, which is:
Other stations which have recorded provisional highest-ever temperatures are Dunsany, Co. Meath at 30.2° (10.7°C above LTA), and Mullingar, Co. Westmeath at 30.4°C (11.2°C above LTA).
Europe is currently experiencing one of the hottest and driest summers on record, with widespread wildfires, excess deaths and water shortages reported in Spain, France and Portugal. The UK has issued its first ever red warning for exceptional heat as temperatures could reach 40°C in some places.
While extremely hot weather does occur within natural climate variability, the kinds of temperature extremes we are seeing in Europe are directly influenced by climate change. Keith Lambkin, Head of Met Éireann’s ‘Climate Services Division’ said “ Due to climate change, we are expecting to see heatwaves become longer, more frequent and intense than in the past. This increase in heat, increases the odds of temperature records being broken.”

What brought the heat to the south-western part of the continent?
High pressure ridge already formed in the South West Europe by 12 June 2022, with an Atlantic low-pressure system between the Azores islands and Madeira, which caused the uprising of warm air in western Europe (source: WMO). This ridge did not move and the temperatures rose gradually day to day. Maximum temperatures were often above 30°C and 8 to 10°C higher than the climatological average.

Provisional temperature records
Saint-Jean-De-Minervois reached 40°C on 16 June, earliest every 40°C in France. Cottbus, Germany temperature 140 year-old record was broken with 39.2°C on 19 June 2022 (since 1888, previous record was 38.9°C set on 29 July 1921). Up to 43°C was observed in Andalusia, Spain. A June temperature record was broken for the western part of Austria with 36.5°C. High temperature records were also set in Czech Republic, Poland and Switzerland.
The heatwave is expected to come to the rest of central and south Europe in the next few days. While a Saharan dust storm will deteriorate air quality in southern France, Italy, Balearic Islands, Spain & the Balkan Peninsula. (source: CopernicusEU) .

“Climate projection models suggest that heatwaves as likely to become more frequent, longer and more intense, start earlier and finish later than in the past.” Keith Lambkin, Senior Climatologist.
Why did Ireland not achieve these high temperatures?
On Saturday, a front lay over the southeast of the country which slowly cleared south-eastwards. A moderate northwest breeze which felt cool and kept the temperatures low. On Sunday, there was a depression of 999 hPa centred to the northwest of Scotland which was tracking eastward. So the air across Ireland is flowing eastward, keeping the continental heat away from our shores.
What is a climatological heatwave in Ireland?
In terms of climate monitoring, a heatwave occurs at a station when there five (5) consecutive days or more observe a daily maximum temperature over 25 degrees Celsius (> 25 °C).
In general in Ireland, heatwaves occur in June, July and August. There has been only one instance of a heatwave beginning in May (Glenties Hatchery, Co Donegal in 2012) and four starting in September, all within the first 2 weeks – one occurring in 1959 and the others occurred in 1991. The peak month for heatwaves in Ireland is July. The average heatwaves is 6 days long. It would be rare to have a heatwave longer than 9 days. The longest heatwave observed is 14 days in Laois and Offaly in August 1976.
Temperatures in June 2022 so far
The highest daily maximum shaded air temperature of 2022 so far is 23.9°C which occurred on Thursday 16 June 2022 at Phoenix Park, Co Dublin.
Currently June 2022 is two thirds completed and is 41st warmest June on record (Island of Ireland long-term series, 123 years) with an average temperature to yesterday of 13.7°C. This value is a half degree above June’s 20th century average (1901-2000) and is currently on average to the 1991-2020 June average. Typically in Ireland, we would expect warmer temperatures towards the end of the month, as the summer progresses. So we are expecting June 2022 to be warmer than 41st warmest. We will have to wait another 10 days to find out however.

Turning colder this week but staying mainly dry
Following the current spell of warm and dry weather it’s going to turn much colder by mid-week as a cooler airmass arrives across Ireland from Scandinavia.
The highest temperature of 2022 so far was recorded on Sunday, with 18.9 degrees reached at Newport Furnace, Co. Mayo. While the pleasant weather will continue on Monday and Tuesday, there is the chance of a few showers at times mainly over the eastern half of the country, generated by more unstable air. However the most significant change will come on Wednesday as a northerly airflow establishes across the country feeding in noticeably colder air from Scandinavia.
Met Eireann meteorologist, Brandon Creagh, said: “It’s going to get noticeably colder from Wednesday as an anticyclone over Iceland will bring cold northerly winds over Ireland on Wednesday and into Thursday. Showers will develop over the eastern half of the country with a slight risk of wintry precipitation over high ground.”
Airmass chart for Thursday 31st March showing a cold (blue) northerly airmass over Ireland, originating from Scandinavia.
The colder spell may come as a bit of a surprise to some as temperatures over the last week have been well into the mid to high teens – above average for the time of year, however from Wednesday we’ll see daytime temperatures drop back down into single figures.
Meteorologist Brandon Creagh added: “It’ll be important to bring plants indoors that are sensitive to cold. Also, farmers and gardeners should be aware that growing conditions will not be as good as they have been recently.”

A sunny, settled and mild week ahead - Tuesday 22 March 2022
High pressure over Europe will become centred over Ireland in the coming days, bringing a good deal of dry and mild weather along with plenty of sunshine.
Met Éireann meteorologist, Aoife Kealy said: “The dry and bright weather that we’ve had over the past few days won’t be going anywhere this week. High pressure is going to stay very firmly in charge so we can generally expect plenty of sunshine and little or no rain.”
“Some very weak fronts will drift into western and northern areas later this week so it’ll be a bit cloudier there at times with a few spots of drizzle but any accumulations will be small. So, even though it won’t be wall-to-wall sunshine, it will be very pleasant still.”
Daytime temperatures will be on the mild side for March and at night temperatures will drop into the low single figures, so a few patches of grass frost are still possible, especially when the skies are clear.
Aoife continued: “It’s the daytime temperatures that are notable though. The average maximum temperatures for this time of year are around 11 or 12 degrees, but the combination of a relatively mild airmass and good spells of sunshine mean that top temperatures this week will widely get into the mid-teens, even hitting the high teens at times.”
This current spell of settled weather looks to last into at least this weekend. Aoife explained: “Although there’s a bit of uncertainty later this weekend, there’s no real sign of this high pressure breaking down until early next week at least. So, this really lovely spell of spring weather won’t be going anywhere too quickly.”
UV and Pollen forecasts for 2022 begin this week
With spring in full force and plenty of sunshine across the country this week, pollen and UV levels will start to increase. You can now find the latest UV and pollen forecasts for 3 days ahead on the Met Éireann website and app.

An unsettled weekend in store - Thursday 10th March 2022
After a changeable week, our weather will remain mixed as we head into the weekend with the potential for heavy rain in some places but also some drier and brighter weather too.
Met Éireann Meteorologist Emer Flood said: “An active jet stream will continue to steer Atlantic low-pressure systems in our direction over the coming days, these will bring spells of heavy rain and strong winds at times.
“Heavy rain will move into the southwest on Thursday night, becoming widespread Friday morning which may lead to localised surface flooding. There is also potential for further heavy rain and strong winds over the weekend with the possibility of warnings being issued. We’re advising everyone to keep a close eye on the forecast for the coming days.”
A yellow rain warning is in place for many southern and western counties from 15:00 on Saturday afternoon until around midnight, where heavy rain along with strong winds will bring a risk of flooding and hazardous driving conditions.
On Friday, rain will be quite widespread and heavy in places, slowly clearing northeastwards in the afternoon. This will be followed by heavy showers with the potential for thunderstorms and hail, which could lead to some localised flooding and hazardous driving conditions.
Some heavy or prolonged showers will continue overnight Friday into Saturday morning. Otherwise, Saturday will start off dry and bright in many areas. However later in the day a low-pressure system will approach from the southwest, with cloud building and winds strengthening as rain arrives across the southern half of the country by evening. Rain may turn to sleet or snow in parts, especially over high ground. Sunday will be wet and windy for many as this same low-pressure system slowly pushes north over Ireland with further falls of sleet or snow possible locally.
Looking ahead to next week there are signs of a quieter and more settled spell on Monday and Tuesday, though this may be short-lived as things once again turn more unsettled around midweek.

Cold snap to bring strong winds and snow - Wednesday 23rd February 2022
A brief cold snap on the way on Wednesday evening and Thursday, with wintry showers of hail, sleet and snow along with strong and gusty winds leading to some impacts in areas.
A cold front moving across Ireland this afternoon (Wednesday 23rd) will introduce a much colder and unstable polar maritime airmass tonight and tomorrow. Met Éireann has issued several yellow weather warnings including yellow level snow/ice and wind warnings. These warnings are in place for many northern and western counties for tonight and Thursday.
Met Éireann meteorologist Emer Flood said, “Temperatures will drop quite quickly this evening with the chance of frost and ice forming, especially for inland and rural areas.
“It’ll be windy tonight too especially in northern and western areas, this helping to drive wintry showers of snow, sleet and hail inland. Some areas especially in the northwest will see some snow accumulations of a few centimetres to lower levels, accumulations elsewhere will be mainly confined to high ground.
“It’ll remain very cold and windy across the country on Thursday with continued snow showers, this leading to treacherous driving conditions from icy stretches and reduced visibility on the roads in places. This polar maritime airmass is quite unstable so we could see some hail and lightning at times throughout Thursday too.”
Temperatures on Thursday will be limited to around 3 to 7 degrees, with the brisk northwesterly winds making it feel much colder.
The Met Office has also issued a snow and lightning warning for Northern Ireland through Wednesday and Thursday.
Commenting on the forecast for the rest of the week, Emer continued: “Following this cold spell, temperatures will recover on Friday and into the weekend with highs of around 8 to 10 degrees. Although there is some rain in the forecast over the weekend, much of this will fall overnight so there’ll be decent spell of dry and bright weather around over the weekend too.”

Turning more unsettled this weekend and next week - Friday 11th February 2022
After what’s been a fairly settled February so far, our weather will turn increasingly unsettled over the weekend with some wet weather on the way on Sunday and early next week.
Met Éireann have issued yellow wind warnings for Donegal, Galway and Mayo and rain warnings for Cork, Kerry and Galway on Friday afternoon and Saturday morning, due to spells of heavy rain and strong winds to mainly southern and western areas. It’ll stay breezy across the country on Saturday with some blustery, heavy showers, followed by a rather wet day across the country on Sunday.
Met Éireann meteorologist, Mark Bowe, said:
“Our weather has been pretty settled so far this year thanks to high pressure never being too far away. But as we head into the weekend and next week we’re going to see a change to more unsettled weather as the jet stream positions itself across Ireland – this will open the door to low pressure systems moving in from the Atlantic.”
“We’re keeping a close eye on the weather forecast for Sunday, as a low pressure will swing up from the south bringing outbreaks of rain through the day. There is likely to be some heavy bursts of rain in places which could lead to some localised flooding, but there’s still quite a bit of uncertainty so it’s best to keep an eye on the latest forecast and warnings, especially if you have plans this weekend.”
Currently ground conditions are either waterlogged or saturated and further rainfall over the weekend and next week will add to water levels, with the possibility of some localised flooding. You can find out more about current ground conditions here https://www.met.ie/forecasts/farming#agri-graphs.
Mark continued: “With further low-pressure systems moving our way early next week there is the potential for further spells of wet and windy weather. We’re keeping a close eye on Tuesday in particular as there are signs of heavy rain in the forecast. With ground levels already waterlogged this could lead to some localised impacts from flooding, so stay keep an eye on the latest forecast and warnings from Met Éireann for your area.”

Críoch fliuch agus gaofar go 2021 agus gaofar ar Lá Caille
Leanfaidh an aimsir de bheith gníomhach go leor go dtí deireadh na bliana, le gaotha láidre in amanna, lena n-áirítear comhaireamh síos na hAthbhliana do roinnt daoine.
Leanfaidh báisteach leanúnach a théann i bhfeidhm ar go leor áiteanna inniu, Déardaoin, isteach anocht. Beidh roinnt titimí troma ann a chruthóidh baol tuilte go háitiúil. Tá Rabhadh Báistí Buí i bhfeidhm go dtí 5am maidin Dé hAoine do Chorcaigh agus Ciarraí, agus tá Rabhadh Báistí Buí eile i bhfeidhm do Ghaillimh agus Maigh Eo idir 5pm tráthnóna inniu (Déardaoin) agus 1am anocht.
Éiríonn sé gaofar tráthnóna inniu sa deisceart, áit a méadóidh gaotha an iardheiscirt ó úr go láidir, agus sínfidh na gaotha níos láidre seo chuig gach ceantar thar oíche. Sroichfidh na gaotha gála mór i gceantair chósta an Atlantaigh, agus beidh rabhaidh gálaí ag teacht i bhfeidhm thar oíche do roinnt limistéar farraige.
Leanfaidh na gaotha láidre go maidin Oíche Chinn Bhliana, Dé hAoine, le gaotha aniar-dheas láidir i go leor áiteanna ar maidin, ag sroicheadh in aice le neart gála uaireanta. Tar éis maidin scamallach den chuid is mó agus roinnt báisteach éadrom ag fanacht i gcodanna, beidh an tráthnóna tirim den chuid is mó le geasa geala. Beidh sé an-éadrom, le teocht tráthnóna 11 go 14 céim.
Rachaidh an ghaoth in olcas go dtí an ghaoth measartha fearúil tráthnóna Dé hAoine, ach beidh an tréimhse níos ciúine seo gearr go leor mar beidh na gaotha ag neartú arís níos déanaí sa tráthnóna ar Oíche Chinn Bhliana. Méadóidh gaotha an deiscirt ó úr go láidir go luath san oíche, leis na gaotha is láidre ar chóstaí an Atlantaigh. Beidh sé fliuch in áiteanna freisin agus ráigeanna báistí ag bogadh soir thar oíche. Fanacht éadrom thar oíche le teocht is ísle de 9 go 11 céim.
Beidh an aimsir don chéad lá de 2022, Dé Sathairn, an-bhrónach le cithfholcadáin, cuid acu sin trom. Beidh tréimhsí geala agus grianmhara ann freisin, áfach. Beidh sé grianmhar le gaotha an iardheiscirt úr, is gaofar in aice le cóstaí an iarthair agus gaotha fós láidir ann. Leanfaidh sé níos séimhe ná an meán, agus beidh an teocht is airde de 11 go 13 céim.
Íomhá ó rith 12Z de Harmonie Déardaoin ag taispeáint clúdach scamall báistí (barr ar chlé), páirc na gaoithe (bun ar chlé) agus teocht (bun ar dheis) don tír ag meán oíche Oíche Chinn Bhliana:

Socraithe agus tirim go príomha sa tréimhse roimh Lá Nollag
Leanfaidh brú ard orainn ag coinneáil ár n-aimsire socraithe agus tirim den chuid is mó tríd an deireadh seachtaine seo agus isteach i laethanta tosaigh Sheachtain na Nollag, cé go bhfuil roinnt comharthaí ann go mbeidh aimsir níos neamhshocraithe ann ó lár na seachtaine ar aghaidh agus b’fhéidir ag éirí níos fuaire thar dheireadh seachtaine na Nollag.
Dúirt meitéareolaí Met Éireann, Deirdre Lowe: “Bainfidh an chuid is mó againn sult as aimsir thirim chiúin roimh an Nollaig, beidh sé measartha scamallach agus feicfidh roinnt spotaí ceo beag fánach nó ceochán i scamall níos doimhne. Rachaidh sé beagán níos fuaire i rith an deireadh seachtaine freisin, agus teocht an lae idir 6 agus 9 Celsius.”
“Fanfaidh sé measartha scamallach i rith na n-oícheanta agus ba cheart go gcoinneodh sé an sioc, cé nach féidir a chur as an áireamh an paiste corr sioc nuair a fhorbraíonn spéartha níos soiléire.”
Leanfaidh an aimsir shocraithe seo ar aghaidh go laethanta tosaigh na seachtaine seo chugainn, cé go bhfuil an chosúlacht ar an scéal go laghdóidh an brú ard de réir a chéile ó thart ar lár na seachtaine ar aghaidh, rud a fhágfaidh go mbeidh ár n-aimsir níos suaite agus muid ag druidim le Lá Nollag. Cé go bhfuil roinnt mhaith éiginnteachta sa réamhaisnéis, tá roinnt comharthaí ann go mbeidh aer níos fuaire á tharraingt ar fud na tíre thar dheireadh seachtaine na Nollag.
Lean an meitéareolaí Deirdre Lowe ar aghaidh: “Tá sé ró-luath fós a rá le cinnteacht cén aimsir ar féidir linn a bheith ag súil leis ar Lá Nollag. Faoi láthair tá an chuma air go gcuirfear brú íseal in ionad an ardbhrú blocála atá ann faoi láthair, rud a mhéadóidh an seans go mbeidh aimsir neamhshocraithe. Tá roinnt comharthaí luatha ann freisin go bhféadfadh tréimhse fuar a bheith ann thar thréimhse na Nollag ach tá sé fíorchinnte fós, mar sin coinnigh súil ar réamhaisnéis Met Éireann is déanaí.”

Dúlagar stoirme ag druidim le hÉirinn Dé Máirt 7 Nollaig 2021
Arna nuashonrú ag Meitéareolaí Liz Walsh ag 6pm Dé Domhnaigh 5 Nollaig 2021
D’ainmnigh Met Éireann Stoirm Barra maidin Dé Domhnaigh (5 Nollaig 2021) agus meastar go rachaidh sé i bhfeidhm ar Éirinn le linn Dé Máirt agus go ceann tamaill Dé Céadaoin. Bainfidh guaiseacha iolracha leis an gcóras seo.
Athróidh tionchair ag brath ar an áit ach áireofar iad
Tá rabhadh gaoithe leibhéal oráiste eisithe do Chontaetha Chorcaí, Chiarraí, Luimnigh, an Chláir agus na Gaillimhe atá bailí ó 6am Dé Máirt go 6pm Dé Céadaoin, agus tá rabhadh gaoithe leibhéal buí in áiteanna do gach contae eile don tréimhse ama chéanna. Is dócha go ndéanfar na rabhaidh seo a nuashonrú agus a mhionchoigeartú agus muid ag druidim níos gaire don imeacht de réir mar a éiríonn rian na stoirme níos cinnte.
Beidh an ghaoth ó dheas go dtí an oirdheisceart i dtreo go luath i rith an Mháirt agus de réir a chéile tiocfaidh sé siar de réir mar a théann an lá ar aghaidh. Mar sin beidh neart na gaoithe ag brath ar do shuíomh agus ar nochtadh don treo áirithe sin. Is dócha go dtitfidh báisteach throm le linn maidin Dé Máirt freisin, iad seo go príomha ar fud na gcontaetha theas agus oirdheisceart le seans tuilte a bheith ann.
Is é an limistéar neamhurchóideach scamallach seo ó dheas ó New Brunswick agus Albain Nua in Oirthear Cheanada ó níos luaithe inniu ná suíomh tosaigh córas brú íseal a dhéanfar Stoirm Barra.

Beidh gaoth láidir i ngach ceantar uaireanta agus tiocfaidh gála i gceantair cois cósta. Is dócha go mbeidh séideáin thromchúiseacha ann. I láthair na huaire táthar ag súil go mbeidh na gaotha is láidre i gcontaetha cósta thiar na Mumhan le gaotha stoirme indéanta uaireanta níos déanaí Dé Máirt.
In éineacht leis na gaotha neartaithe beidh seal de bháisteach throm ar an Máirt, agus cithfholcadáin troma ina dhiaidh oíche Dé Máirt agus Dé Céadaoin. D’fhéadfadh cuid de na cithfholcadáin a bheith ina sleá nó sneachta ar thalamh ard.
Mar gheall ar thaoidí earraigh, tonnta an-ard agus leibhéil borrtha móra, d’fhéadfadh tuilte cósta tarlú feadh chóstaí na Mumhan agus dheisceart Chonnacht.
Tionchair Féideartha
Is dócha go gcuirfidh gaotha an-láidir agus séideáin dhíobhálacha isteach ar bhriseadh cumhachta, crainn tite nó craobhacha nó smionagar eile.
Chomh maith le tuilte cois cósta, tabharfaidh báisteach throm nó cithfholcadh tuilte áitiúla. Is dócha go gcuirfear isteach ar thaisteal uaireanta mar gheall ar ghaotha láidre, droch-infheictheacht, tuilte áitiúla agus drochchoinníollacha dromchla de bharr clocha sneachta, sneachta nó sneachta ar thalamh ard.
Réamhaisnéis mhionsonraithe
Forbróidh dúlagar stoirme i lár an Atlantaigh Dé Luain mar thoradh ar bhrú dinimiciúil ón Jetstream san atmaisféar uachtarach. Doimhneoidh an córas ísealbhrú go tapa agus é ag dul soir ó thuaidh thar an Atlantach agus ag druidim le hÉirinn ar Scairdsruth láidir siar.
De réir mar a bheidh an dúlagar ag druidim le hÉirinn, tiocfaidh moilliú air agus éireoidh sé measartha mall ag gluaiseacht tríd an Máirt agus an Chéadaoin. Níl rian cruinn agus uainiú an dúlagar cinnte. Faoi láthair táthar ag súil go sroichfidh sé íosbhrú de 952 hPa tráthnóna Dé Máirt ag timpeall 100 muirmhíle nó 185 Km in iarthar na hÉireann. Líonfaidh an dúlagar go mall agus méadóidh a bhrú lárnach de réir a chéile agus é ag bogadh go mall soir thar Éirinn trí oíche Dé Máirt agus Dé Céadaoin, ag glanadh soir ó dheas trí oíche Dé Céadaoin ar deireadh.
Tá forbairt agus rian an dúlagar tríd an Luan, Dé Máirt agus Dé Céadaoin le feiceáil sna cairteacha thíos.
Réamhaisnéis na Gaoithe
De réir mar a bheidh an dúlagar ag druidim le hÉirinn, neartóidh na gaotha ó dheas trí oíche Dé Luain agus go luath Dé Máirt le gálaí nó gálaí láidre ag forbairt feadh chóstaí uile na hÉireann agus Mhuir Éireann. Forbróidh gaotha athraitheacha cioclónacha de réir mar a ghluaiseann an dúlagar ar fud na hÉireann. Níos déanaí Dé Máirt agus trí oíche Dé Máirt, forbróidh gaotha an-láidir an iarthair i gcontaetha chósta an iarthair. Tá an chuma ar an scéal faoi láthair go dtarlóidh na gaotha is láidre i gcontaetha cósta thiar na Mumhan agus Co. na Gaillimhe.
Léirítear é seo ar Innéacs Réamhaisnéise Foircní ECMWF le haghaidh séideáin gaoithe agus freisin ar na réamhaisnéisí cinntitheacha thíos.
Réamhaisnéis Báistí
Níl cinnte cén t-am a thiteann báistí ar fud na hÉireann a bhaineann le dúlagar an Atlantaigh. Léiríonn an tsamhail reatha tuartha go dtiocfaidh báisteach throm in iarthar na hÉireann níos déanaí oíche Dé Luain agus go bogfaidh sé soir ar fud na tíre maidin Dé Máirt. Leanfaidh cithfholcadáin ón iarthar tráthnóna Dé Máirt agus leanfaidh siad ar aghaidh go dtí oíche Dé Máirt agus Dé Céadaoin. Beidh cuid acu geimhridh, ag titim mar chlocha nó sneachta le sneachta ar thalamh ard. D’fhéadfadh stoirmeacha toirní iargúlta a bheith ann freisin.
Coinníollacha Cósta
Táimid i dtréimhse de Thaoidí Earraigh, agus táthar ag súil go n-ardófar leibhéil chósta Dé Máirt agus córas domhainbhrúite ag druidim ón Atlantach as a dtiocfaidh gaotha láidre, tonnta arda agus leibhéil mhóra borrtha. Táthar ag súil leis na leibhéil borrtha is mó ar chóstaí an Atlantaigh. Tá éiginnteacht fós ann idir ritheanna samhlacha ar uainiú agus cosán an chórais ísealbhrú, a imreoidh tionchar ar an leibhéal borrtha a bhfuiltear ag súil leis go háitiúil feadh an chósta, agus ba cheart go laghdódh an neamhchinnteacht de réir mar a thagann rití samhlacha amach anseo ar fáil.
