Met Eireann has issued a Status Yellow High Temperature warning for the whole Ireland as the country is set to sizzle in temperatures of close to 30C over the weekend.
The national forecaster said that the entire country would see "very warm or hot" conditions on Friday and Saturday with maximum temperatures reaching from 27C to 29C.
And it will remain hot at night, with temperatures set to stay above 15C. However, in coastal areas - particularly in the northwest - temperatures may not be as high due to sea breezes.
Met Eireann has warned that the heatwave may lead to heat stress, especially for the more vulnerable of the population, high solar UV index and risk of water related incidents.
The weather warning for the entire country will come into effect at 12pm Friday and will remain until 6am on Sunday.
Meanwhile, a separate Status Yellow High Temperature weather warning was issued for Leinster and Munster and will be in place from 12pm Thursday until 12pm Friday.
Temperatures in the south and east of the country are expected to hit 29C - and possibly higher.
Met Éireann said: "Very warm with sea breezes developing this afternoon, otherwise there will be little wind. Highest temperatures generally between 24 to 29 degrees, but likely to reach 30 degrees in localised parts of Leinster and Munster."
And we could see record breaking temperatures as it could get as hot as the low 30s on Friday. The highest temperature ever was 33.3C detected at Kilkenny Castle in June 1887.
Met Eireann said: "Friday will be a hot and sunny day with highest temperatures generally between 25 to 30 degrees, possibly reaching the low 30s in a few inlands spots of Leinster or Munster. Not as warm near coasts, with sea breezes developing in the afternoon."
