Autumn Takes Hold in Ireland with Dry Days, Misty Nights, and Cooler Temperatures Ahead

Autumn Takes Hold

The pattern has turned. After weeks of milder air, Ireland is now firmly in autumn. The days are cooler, the nights are sharper, and the first patches of mist and fog are showing up in the early hours.

Sunday’s Weather

Sunday opens bright and dry for much of the country, but showers push into the north and west by afternoon. They drift south through the day before fading out in the evening. Highs will reach 11 to 15 degrees. By night, the skies clear and the air cools quickly. Temperatures fall to 2 to 6 degrees, low enough for fog to creep into valleys and fields.

Cool Nights, Bright Starts

Monday begins crisp and sunny, the kind of morning that signals the season’s change. Cloud thickens from the north as the hours go by, though rain is not expected. Daytime highs reach 11 to 14 degrees. The night will once again be cool, with lows between 3 and 8 degrees. Mist and fog will form again in sheltered spots.

Midweek Outlook

Tuesday keeps the settled pattern going. It will stay dry, with occasional sunshine and highs of 12 to 14 degrees. Wednesday turns cloudier, especially near Atlantic coasts, where patchy drizzle may develop. Elsewhere conditions stay mostly dry, with afternoon highs of 13 to 15 degrees.

High Pressure Keeps Control

Met Éireann expects high pressure to remain in place later in the week. That means more of the same: calm days, cool nights, and fog forming at dawn. Autumn has arrived, and the rhythm is now clear—dry air, steady sunshine, and crisp evenings that settle into silence once the mist rolls in.
