Met Éireann has forecast that this week’s warm spell will last until the weekend with temperatures set to reach up to 26C in many parts.
Yesterday, it recorded a temperature of 27.6C at its Valentia Observatory in Co Kerry, which it said was the warmest day in Ireland since 13 June.
Highs of 26C are forecast until Friday, with 20-25C expected on Saturday.
However, Met Éireann has also warned of warm, muggy nights with temperatures staying between 13-17C.
In a post on X (nee Twitter) this morning, it said: “A number of hurricanes, tropical storms and depressions in the Atlantic are pumping warmer air into the upper atmosphere, allowing high pressure to build in from the east. That is bringing this warmer spell.”
