Some of the year's highest temperatures were recorded in the State yesterday and today could be even hotter as a large area of high pressure passes slowly over Ireland.
The highest recorded temperature yesterday was 27.4 degrees in Kilkenny, according to Met Éireann, with several inland weather stations logging similar values.
In the midlands, temperatures may climb as high as 29 degrees today with most parts of the Republic basking in the mid-20s. An easterly sea breeze will cool things down a little for coastal regions.
"The good weather looks likely to continue although there is a danger on Tuesday that there could be a couple of thunder storms as the humidity builds," said Aidan Nulty of Met Éireann. "Temperatures will return to more normal levels after that but it should still be nice, summery weather towards the end of the week and into the weekend."
With people flocking out into the sunshine, it was a busy weekend for the coastguard services with around 40 incidents recorded. Most related to motor boats breaking down near the coast, with several vessels having to be towed ashore.
A couple who got stuck on cliffs near Malin Head, Co Donegal, were rescued yesterday evening, and although other minor incidents were reported there were no serious injuries.
"For people who get into trouble on the water, the life-jacket is the key," said a spokesman for Valentia Coastguard last night. No matter how strong a swimmer you think you are, you should always wear a lifejacket," he said.
