Sunseekers cool off on the beaches as mercury heading towards 27C
Forecasters are predicting that today could be the hottest day of the year.
Temperatures soared as high as 26C in many parts of the country yesterday, with the sunny south-east particularly living up to its name.
But highs above 27C are now predicted for parts of the country today and tomorrow, which may beat the previous record for the year which was set in mid-June.
Met Eireann's John Eagleton said that the highest temperatures recorded yesterday were in Carlow's Oak Park, as well as in parts of Dublin and Claremorris, Co Mayo.
Yesterday was the warmest of the current spell but the forecaster reckons that the best is yet to come.
He said: "We are at the height of the summer now. It reached 27 degrees on June 18, and I think it is going to be higher this time, definitely between today and Friday."
The western half of the country and parts of the south woke to cloud cover yesterday which had began to dissipate by the afternoon.
However, Mr Eagleton said that things are likely to be better there today.
"For the coming days it will be much the same. Generally speaking, the west will be better today than it has been," he added.
The sunshine and humid conditions that have been around all week are set to continue for the coming days, and it is likely to be the weekend before things cool down.
Adrian Cummins from the Restaurant Association of Ireland said that he anticipates diners will flock towards the coast where businesses "will do extremely well".
Age Action, an advocacy group for elderly people, has called upon the public to be more aware of older people who may be more vulnerable in the heatwave.
The temporary bathing ban that was in place at popular Dublin coastal spot Sandymount Strand has now been lifted after the city council carried out a number of tests on the water there since it was put in place on Monday.
A spokesperson for the authorities said yesterday that the water quality was now "in compliance" with the required standards.
And as people hit the coasts and popular water amenities, Drinkaware is encouraging people to be more vigilant as they cool off, and to avoid becoming complacent in the water. It said people should not swim or get involved in water-based activities after they had drunk alcohol.
