Met Éireann also said that Wednesday night was provisionally the first tropical night in Ireland for 20 years, with Valentia in Co Kerry not observing any temperature under 20.5 degrees.
Tropical nights, meaning shaded air remains above 20 degrees all night, are rare in Ireland, having previously only been recorded six times.
Met Éireann meteorologist Aoife Kealy said: “It looks like the high pressure that has brought us this hot and settled weather will gradually break down through the weekend and we’ll lose the very high temperatures.
“It’ll still be warm though, with temperatures into the low to mid 20s Celsius across the country on Saturday and Sunday.”
An Orange Forest Fire Warning issued by the Department of Agriculture due to the hot and dry conditions expired at 12pm on Friday.
