Temperatures could reach 29 degrees
People are being urged exercise caution while enjoying the hot weather this weekend.
It is set to be the hottest day of the year so far with temperatures of up to 29 degrees in some areas.
While breezes will keep coastal areas cool, Met Eireann's meteorologist Aoife Kealy says people still need to be careful when out in the sun.
Roger Sweeney from Water Safety Ireland is asking swimmers to take care in the water.
He thinks many people have not swam in a long time.
When going for a swim in open water, never swim alone and get local knowledge from swimmers in the area.#BetterSafeThanSorry
