A possible 'heatwave' over the coming days could bring some of the hottest weather of the year, with parts of the country set to experience temperatures close to 30 degrees on Tuesday
A possible 'heatwave' over the coming days could bring some of the hottest weather of the year, with parts of the country set to experience temperatures close to 30 degrees on Tuesday, according to one weather expert.
Commenting on the latest Met Éireann HARMONIE models, Alan O’Reilly of Carlow Weather says large sections of the country, particularly in the midlands, are likely to experience soaring temperatures under strong August Sunshine.
The forecast map for 4pm on Tuesday shows much of the Mid-West sitting between 27°C and 30°C, with the warmest conditions expected in County Tipperary.
Coastal areas can expect temperatures to be a bit cooler with sea breezes but the heat will still be well above average for mid August.

Looking ahead to the next few days, Siobhan Ryan, meteorologist at Met Éireann, said it will be "very warm across the country".
Confirming there is a chance of a heatwave (five consecutive days of temperatures above 25°C) this week, she cautioned there will be thundery downpours too in many places.
Ms Ryan told the News at One on RTÉ Radio 1 that temperatures on Tuesday "could easily creep up to 27 or 28 degrees".

Met Éireann is advising people to take precautions in the hot weather, including staying hydrated, applying SPF regularly, avoiding strenuous outdoor activity during peak heat, and keeping vulnerable people cool.
If temperatures do hit 30 degrees, it would make Tuesday one of the hottest days of the year.
The highest temperature recorded in Ireland so far in 2025 was 31.1 °C, measured at Mount Dillon in Count. Roscommon on Saturday, July 12.
The sunshine is a welcome boost for holidaymakers but also a reminder of the growing frequency of extreme weather events linked to climate change.
