Ireland set to sizzle in 28 degree heat as hottest days of the year expected this week

Ireland's Weather Channel has confirmed that the summer weather is finally on its way for June

Cathal Nolan from Ireland's Weather Channel has delivered very welcome news on Monday as he has confirmed "with certainty" that the country will experience its hottest days of the year this week following a dreary start to June. 

The weatherman explained that Ireland will get this blast of heat from Wednesday onwards as very warm air from the Iberian Peninsula will be pulled northwards on the back of a southerly airflow.

So far, the high temperatures look set to sizzle the country on Wednesday, Thursday, Friday, Saturday and potentially on Sunday. 


Cathal said: "The maximum temperatures we experience will depend very much on your geographical location, wind speed, cloud cover and proximity to the coast. In such situations the west and north are usually best.

"Highs during this predicted hot period are likely to reach anywhere between 26-28 degrees Celsius, with some model outlier indicating temperatures will struggle to break 25 while some show highs of 31."

He concluded: "In terms of its longevity it appears as though this spell of hot weather will persist from Wednesday right the way through the weekend and into the early days of next week as well, with mostly dry weather from today.

"In summary we can say Ireland is about to experience its warmest spell of weather this year, with temperatures in the mid or high 20’s, with some warm sunshine and an outside chance of a thundery shower later in the week."

In the meantime, Met Éireann has predicted mostly dry days on Monday and Tuesday with just scattered showers in parts of the country and plenty of sunshine. 

Highest temperatures on Monday will range between 17 and 23 degrees, while highest temperatures on Tuesday will be slightly lower between 16 and 22 degrees.
