Parts of Cork, Tipperary and Kilkenny could see temperatures reaching 26C today, according to Met Éireann.
his comes as temperatures are currently above average for the month of August as the country experiences a heatwave.
The forecaster said a heatwave consists of temperatures above 25C in the same location for five consecutive days.
Offaly and Laois along with parts of Tipperary, Kilkenny and Kildare will see temperatures reach 25C today.
Many counties will see temperatures above 20C today with large parts of Ulster, Leinster and Munster topping 22C.
Meteorologist Paul Downes said the hot spell in July was a “short, sharp burst”, however, this time it is more prolonged, and it is going to be quite warm and muggy overnight.
He said some areas along the east coast could experience temperatures in the high teens overnight making for quite uncomfortable sleeping conditions.
Mr Downes said the highest temperature recorded in August was 31.5C and it is “unlikely” that it will be surpassed but temperatures could reach 30C towards the end of the week.
He said temperatures went a little bit above Met Éireann’s forecast model suggestions on Monday. He said Saturday currently looks to be the hottest day of the week so far.
Temperatures will widely reach 25C across the country on Wednesday with highs of 27C possible.
Mr Downes said the UV index will also be quite high this week as there will be less cloud cover and more sunshine.
“On Thursday, there will be more widespread temperatures above 26C over much of Leinster and Munster and the coolest parts will be up around Donegal and the fringes of Mayo and Sligo but you’re still looking at 21C to 24C in those regions,” he said.
“The entire southern half of the country could see temperatures reach up to 28C or 29C on Friday.
“Saturday is a similar sort of day with maybe a degree higher, it could reach 29C in some parts. It will be cooler though over northern fringes with 21C to 24C forecast.
“The southeast of country will be the warmest on Sunday with temperatures possibly reaching 29C in Carlow and Kilkenny.”
