As the last weekend of September 2026 begins, Ireland is experiencing its typical mixed weather. If you have plans, whether traveling or staying home, you'll want to check the forecast. We're expecting everything from sunshine to heavy, thundery downpours, and the usual gusty Irish winds are quite noticeable. It's the kind of weather that reminds you to dress in layers.

Saturday: Changing Skies

Today, Saturday, September 26th, started pleasantly for many, with some good sunny spells this morning. However, the "well scattered showers" Met Éireann mentioned have appeared in various parts of the country.

As the day continues, the situation shifts. Expect clouds to really build up through the afternoon and into the evening. These aren't just light clouds; the showers are forecast to become much more frequent. So, if you were hoping for a completely dry afternoon, you might be disappointed, especially as evening approaches.

Temperatures are relatively mild for late September, reaching highs of 15 to 20 degrees Celsius. The east of the country will be the mildest. However, this warmth comes with moderate to fresh, and occasionally gusty, south to southwest winds. If you're near the western or northwestern coasts, these winds will be particularly strong.

Tonight: Rain Moves In, Especially South

Saturday night will offer a brief dry period early on, with some clouds, clear spells, and only isolated lingering showers. But this won't last. The forecast shows clouds building from the southwest, with rain following.

This rain should reach most areas by the latter half of the night, with only the very northeastern parts of the country remaining dry until morning.
