A warm-weather warning will come into effect for parts of the country later today.
Temperatures are set to hit in excess of 27 degrees in parts of the south and west, according to Met Eireann, who've issued a yellow level alert.
It's in place for Galway, Mayo, Clare, Cork, Kerry and Limerick from 1pm until 7pm.
Meanwhile, Water Safety Ireland is warning people to stay safe when swimming in the hot weather today.
Elsewhere, a swimming ban remains in place at a number of Dublin beaches including Dollymount, Sandycove, Seapoint and the Forty Foot.
Heavy rain earlier this week caused an overspill at the Ringsend treatment plant leading to sewage entering the sea.
Tests results from the effected beaches are due back today with hopes that the ban will be lifted.
The message from Met Eireann is that "Today will be a very warm day and the Solar UV index is very high, so do take care in the sunshine. Top temperatures will reach of 22 to 28 degrees"
