Today is to be the hottest day of the year

It's expected temperatures will reach the mid to late 20s in some places later

However the west of Ireland is set to be a little cooler.

Alan O'Reilly from Carlow Weather says most parts should see good sunny spells:

"There will be really warm weather with lots of glorious sunshine in many parts of the country, it's really just the West Coast that's going to be a little bit cooler and under some cloud, but really away from the West Coast, it's going to be a warm and fabulous day with good sunny spells, and it's going to feel warm and humid, possibly even hot with 26 or 27 degrees."
