Forecast issued at: Tuesday 22nd June 2021 14:00


Over the past 7 days, rainfall totals have been well below average for most of the country, with much of the east recording less than 5mm of rainfall. Conditions were slightly wetter along western coasts where 10 to 15mm of rainfall fell, equating to about 50 to 80% of expected rainfall for this time of year. There'll be some rain or showers at times over the next 7 days but overall rainfall amounts are expected to be near-average or below average with around 10-15mm forecast generally.


Mean air temperatures over the past week ranged from between 11to 13 degrees from west to east. Conditions were around a degree or two cooler than normal over the past week in the western half of the country, with mean air temperatures in the east normal or slightly below normal for the time of year. Over the next week, mean air temperatures will increase to 13 or 14 degrees in the northwest, which is normal for this time of year. However high pressure will bring warmer temperatures over the rest of the country with and average mean air temperature of 15 or 16 degrees forecast, which is 2 to 3 degrees above normal. Soil temperatures have generally been 2 to 4 degrees higher than normal the past week, ranging around 14 to 19 degrees, highest in the southeast. Soil temperatures were closer to normal in the west. Mean soil temperatures are expected to remain above average for the coming week.


Sunshine values the past 7 days have been near average or above average. Dublin Airport reported the most sunshine with 54.6 hours recorded there, 1.4 times the average. Slightly below average sunshine amounts were recorded near western coasts, with 33.9 hours experienced at Valentia. Sunshine amounts will vary this week. There will be some extended period of sunshine in the east today, but it will turn more showery through the midweek before settling down again later in the weekend and next week.

Drying Conditions

Some drying in the east today in good sunny spells and highest temperatures in the mid to high teens though winds will be mainly light to moderate. Drying conditions will become poor in the west and north this evening with outbreaks of rain developing. Drying conditions will generally be mostly moderate or poor throughout Wednesday but improving for a time on Thursday before further rain pushes south later on Thursday.


Similarly, there will be good spraying opportunities today in the east but rain and drizzle in the northwest will spread east towards the evening, with lighter winds. Some limited spraying opportunities early Thursday but better options for Sunday and next week.

Field Conditions

Soils have positive moisture deficits nationwide across all soil types. Generally ranging between 20 to 60mm with driest soils in eastern counties. Soils are the least dry in the northwest and in western fringes of Munster, with deficits of around 10 to 15mm. Although there will be rain and showers through the midweek, high pressure looks set to build over the weekend meaning soil moisture deficits will remain much the same or increase slightly in the next 7 days.

Further Comments

A blight advisory is in effect for Donegal, Mayo, Sligo, Leitrim and Galway: Conditions conducive to the spread of potato blight will develop in western and northwestern counties from Wednesday evening (23/06/21) through Thursday (24/06/21).
