There’s also a red forest fire warning in place.
The warm weather is set to continue over the bank holiday weekend, according to the latest forecast from Met Éireann.
The national forecaster has summarised how things will look across the three days and temperatures are expected to range from 20 to 25 degrees.
A forecaster said: ”Warm and mostly dry weather through the Bank Holiday weekend and current indications are that it will continue for early next week before turning cooler and less settled”.
Yesterday, Roscommon saw the highest temperature in the country at 26.8 degrees.
Meanwhile a red forest fire warning is in place, with people being told not to light fires or have barbecues on forest lands or other high risk areas.
The alert means there’s an extreme fire risk, with easy ignition and rapid spread.
It will remain in place until Monday.
