Ireland is set for another spell of exceptionally warm weather this week, with temperatures forecast to climb as high as 28C in parts of the country before potentially reaching 30C by Friday.
The hot conditions come just weeks after Ireland experienced two successive heatwaves, with Met Éireann forecasting that the warm weather will continue to build throughout the week.
Tuesday is expected to bring temperatures into the low to mid-twenties across much of the country, with the warmest conditions in the east and southeast. According to Met Éireann, "Temperatures will generally rise to the low to mid-twenties, a little higher in parts of the east and southeast, where temperatures will possibly reach 27 or 28 degrees."
The warmth is expected to continue on Wednesday, with much of the country enjoying dry conditions and sunshine. The forecaster said: "Highest temperatures will range from 18 to 20 degrees in the northwest and west, but generally in low or mid-twenties, highest across Leinster, where temperatures will be even a little higher locally, up to 27 or 28 degrees."
Looking further ahead, Met Éireann says the weather will become even hotter as the week progresses.
In its national outlook, the forecaster said: "Overall a lot of dry weather for the rest of the week and weekend with sunshine and becoming increasingly warm. Indeed getting hotter, especially later in the week and into the weekend."
Friday is currently expected to be the hottest day of the week, with Met Éireann forecasting: "Hotter than previous days with temperatures reaching the mid to high twenties, possibly touching 30 degrees in places."
The settled weather is expected to continue into the weekend, with temperatures remaining well above average across much of the country.
According to Met Éireann: "It's going to continue very warm or hot by day with temperatures generally in the mid to high twenties, possibly a little higher in places... Very warm and muggy by night with temperatures not falling below 16 to 19 or 20 degrees."
While sunshine is expected to dominate, the forecaster has also warned that isolated showers and thunderstorms could develop later in the week and into the weekend.

A recent study found the breaking temperatures people experienced in May could not have been possible with climate change.
This study, conducted by climate scientists, found the weather experienced on May 26 was the result of human-caused climate change.
Exceptionally hot temperatures were experienced, thanks to a combination of high pressure and an unseasonably hot tropical airmass across Ireland.
The record for the highest daily temperature during May was beat by more than 2 degrees, with the previous record set in Ardfert, Co Kerry in 1997 with 28.4C.
Temperatures of 30.6C were recorded at Shannon Airport in Co Clare. Overall, Met Éireann said that May 2026 was the seventh warmest May since 1900.
The forecaster found that the increase in the monthly May temperatures was between 2.1 and 2.5C, a remarkable increase under any circumstances.
According to this rapid weather attribution study, which was conducted by researchers at Maynooth University, it was found that none of this would have been possible in a pre industrial climate, and could only have happened with human induced climate change, usually the burning of fossil fuels.
