Dublin had its driest June in 40 years.
According to Met Eireann's latest forecast, the Phoenix Park recorded only 11.5mm of rainfall last month - the lowest levels on record since 1975.
It was a little chillier than usual at the beginning of the month with average temperatures dipping by 1C around the country.
The lowest average temperature was 11.7 degrees at Knock Airport, Co Mayo, and Malin Head, Co Donegal.
The heatwave hitting the UK and Europe made its way across the sea, making the last day in June the hottest day of the year.
Temperatures soared to 25.6C in the Phoenix Park, the highest on record since 1996.
It was a record-breaking day at Malin Head, Co Donegal, with temperatures reaching 24.7C, making it the hottest June 30 since 1978.
Dublin had its sunniest day of the month, with 15.7 hours of sunshine recorded at Dublin Airport on June 10.
But don't get too excited, because the dry and sunny spell is due to come to an end.
"We had such a promising start to the summer," said Met Eireann forecaster Willemien Phelan.
"It was bright and sunny just as the school kids started their holidays, but temperatures will drop this weekend."
Scattered showers will start to fall in the south late this evening.
"So if you're planning to go camping, make sure to bring plenty of waterproofs and some umbrellas," Ms Phelan advised.
Tomorrow morning will be bright and dry but patchy outbreaks will occur in the afternoon. However, things will take a turn for the worse.
"On Sunday, the rainfall will be widespread and somewhat heavier," Ms Phelan said.
"Next week it will be overcast and unpredictable. It will be definitely cooler.
"After that promising start it seems things are going back to normal."
The drop in temperature may come as a welcome relief to some.
"The past few days have been quite muggy and humid," said Ms Phelan.
"That will ease in the coming days."
