Met Éireann has said that a prolonged spell of very warm weather is expected, with temperatures exceeding 25C over the coming days.
An advisory from the forecaster, which is in effect from tomorrow until next Tuesday, states that daytime temperatures will exceed 25C, possibly climbing to 30C in parts of the country.
Ailís Hankinson, forecaster with Met Éireann, said that from Friday the “main heat” will come into effect, with temperatures climbing to the high 20s.
“We’re seeing a signal for the warmest temperatures really from the weekend in Munster, south Connacht maybe west Leinster,” she said.
Speaking on RTÉ’s Morning Ireland, she added: “We’re looking at a prolonged spell really of very warm and possibly hot weather.”
Ms Hankinson said that the warm weather is due to an area of high pressure currently located to the south of Ireland and is “building a bit of a ridge over the south of the country”.
She said there was a bit of a “waving weather front” lingering over the north-west of the country, keeping it a bit cloudier.
However, Ms Hankinson said the high pressure will spread further northwards over the next few days, making the sunshine more widespread.
