The weekend is set to be a mixed bag in terms of weather with a wide range of events happening over the next three days, including Longitude festival at Marlay Park.
Met Éireann forecaster Evelyn Cusack said “it’s a typical Irish summer weekend with mixed weather and no extremes”.
“It will be quite mild with warm sunshine at times and temperatures peaking into the low 20s. There will be some cloud coming in from the Atlantic bringing some showery rain from time to time but sunshine as well.”
There will be some sunny spells, but generally cloudy, misty, wet weather will develop over parts of Ulster and Connacht in the afternoon, with the rain turning persistent and heavy later. Much of east Munster and south Leinster should remain dry with top temperatures of 17-22 degrees.
