After a very wet and unsettled July and August, fine and largely settled conditions have returned for the first week of September.
These warm conditions are due to an area of low pressure to the west of the Iberia which, coupled with high pressure over Scandinavia is advecting warm and humid air over Ireland.

Meteorologist with Met Éireann Emer Flood explains, “High pressure looks set to dominate our weather for the rest of the week bringing generally fine and settled conditions. Daytime temperatures will reach into the early 20s for much of the country, with parts of the south midlands reaching 25°C or above. These warm daytime temperatures will be coupled with nighttime temperatures not dropping any lower than the early teens leading to some uncomfortable sleeping conditions in the coming days.

Last night a minimum temperature of 20.7°C was recorded at Valentia, which is provisionally the first recorded tropical night of the year.
Climatologist with Met Éireann Dr. Sandra Spillane states, “We recorded temperatures greater than 25.0°C at a number of our stations yesterday (Monday the 5th of September) so we’ll be keeping a close eye on temperatures over the coming days to see if heatwave criteria are reached”.
A heatwave occurs at a Met Éireann station when the daily maximum shaded air temperature is greater than twenty-five degrees Celsius (> 25.0°C) for five or more consecutive days. More information on hot weather conditions can be found in our Summer Centre.
So will the fine weather stay with us for the weekend?
Emer continues, “While many areas will see fine and dry weather right out the weekend, there will be showers at times, in the west on Wednesday, but further east towards the end of the week with the chance of some thundery downpours.”
“The models are showing a breakdown to cooler and more unsettled weather early next week although there is still a lot of uncertainty at this stage”.
