Highest temperature ever recorded in Ireland could be broken in days as Met Eireann issues night-time warning

Met Éireann has advised that Ireland could experience a number of "tropical nights" in the coming days with the country set to bake in a mini-heatwave.

The national forecaster has issued a rare high temperature warning valid from 3pm on Wednesday for a full week. They said: "Ireland will experience a hot spell Sunday and into early next week. Daytime temperatures will widely reach the high twenties, possibly exceeding 30 degrees in some locations. Remaining uncomfortably warm overnight too."

Specific weather warnings are possible in some areas as the weather system develops, while Irish Meteorologist Paul Downes also says "the nighttime temperature will 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.”

Met Éireann adds: "It will also be very warm by night, particularly on Monday night."

In their forecast for the advisory period, Met Éireann says: "There will be a short spell of hot weather this weekend and early next week, with daytime temperatures widely reaching the mid to high twenties and possibly the low thirties.

"Most areas will be dry with sunny spells this morning [Thursday], although there will be the odd shower in Ulster. It will generally become cloudier for the afternoon and evening with a few further showers in the northern half of the country. Highest temperatures this afternoon of 16 to 23 degrees, warmest near the south coast where the best of the sunshine will be. Northwest breezes, light to moderate in strength," their forecast continued.

Looking to Friday, they say the morning will be "largely cloudy with scattered light rain but it will brighten up through the afternoon and evening with spells of warm sunshine developing. Highest temperatures of 17 to 24 degrees, warmest in the south and southeast. It will be cooler along north facing coasts due to a light to moderate north to northwest breeze."

They say Saturday morning will be dry with spells of hazy sunshine, however, they added, "it will become cloudy at times during the afternoon and evening with isolated showers possible. Warm with highs of 20 to 25 degrees in a light south to southeast breeze."

"There will be a few light showers early in the night but it will become dry with clear spells overnight. Very mild with temperatures remaining above 12 to 15 degrees, in a light south to southeast wind."

Met Éireann predicts "very warm and dry" weather on Sunday with long spells of sunshine. Highest temperatures of 22 to 27 degrees. They say it will be warm and dry too overnight with "temperatures staying above 13 to 16 degrees" in a light south to southeast breeze.

Monday appears to be the hottest day in the forecast with Met Éireann predicting "temperatures widely reaching 26 to 29 degrees."

"Temperatures of 30 or 31 degrees are possible in some areas," they added, while "isolated showers may occur but for the most part it will be a dry and sunny day with light south to southeast winds."

"Monday night will feel very warm as temperatures stay above 16 to 19 degrees. It will be dry with light winds and mostly clear skies.

"Very warm or hot conditions are likely to continue into Tuesday but current model indications are for a showery and thundery breakdown from Tuesday night, bringing an end to the hot spell," Met Éireann's latest forecast concluded.

Meanwhile, the Weather Alerts Ireland Facebook page says "the latest GFS model is forecasting 33 degrees on Monday, adding, "this would be one of if not the hottest days in Ireland ever recorded."

The highest temperature ever was 33.3C detected at Kilkenny Castle in June 1887. Last summer, temperatures soared during a July heatwave but peaked at 30.8C at Mount Dillon in Roscommon. It's likely that temperature will be broken early next week with the hottest day of 2022 but it remains to be seen if the 1887 record will be surpassed.
