Sunshine to stay but pack a brolly
Pack a sun hat and a brolly as a low pressure system moving in today will generate the odd shower along with some sunny spells.
While the mercury won't hit the 25.7C mark as it did in Malin Head, Co Donegal, yesterday, it will still be warm and pleasant enough over the next few days, according to Met Eireann forecaster Liz Coleman.
"While temperatures are falling back to normal, it will still be nice," she told the Herald.
While there will be some cloud at times, that doesn't mean ruling out days at the beach, especially along the east coast where it should remain mostly dry with temperatures a few degrees above normal at 24C or 25C.
Tomorrow will remain warm and mostly dry in the east and north, with daytime highs of between 20C and 24C.
Daytime highs will drop to between 18C and 21C in a mix of sunny spells and showers forecast for Friday and over the weekend.
The country is on the outer fringes of another heatwave engulfing the Continent this week.
Irish holidaymakers heading to Europe have been warned to take precautions as record-breaking temperatures in France and the Netherlands are expected to exceed 40C.
Irish Travel Agents Association chief executive Pat Dawson urged tourists to stay hydrated and avoid direct sunlight at the hottest periods of the day and follow local advice.
Temperatures in France hit 40C yesterday and Paris authorities have activated a heatwave plan to ensure elderly people are checked on regularly and rooms are set aside for shelter.
Meanwhile in the UK, where temperatures are expected to reach 34C in London today, there have been calls for heatwaves to be named in the same way as winter storms to warn people of the dangers of the sweltering heat.
