Ireland Weather Forecast: Get Ready for a Blustery Wednesday and an Unsettled Week Ahead

If you were hoping for a gentle start to your Wednesday, you might be out of luck, especially if you're waking up in the north or east. Today, Wednesday, October 21, 2026, is kicking off with a rather wet and windy bang for many, a theme that looks set to dominate the coming days, according to the latest from Met Éireann.

It often feels like autumn in Ireland is a constant negotiation with the elements, doesn't it? One minute you're enjoying a crisp, sunny spell, the next you're bracing against a squall. This week, it seems we're firmly on the "brace yourself" side of that equation.

What to Expect Today: Wednesday, October 21

The morning began with significant rain and strong winds, particularly across the northern and eastern parts of Ireland. If you're in East Ulster, you might still be seeing some of that lingering wet weather as the morning progresses. But don't despair entirely; there is a shift on the horizon.

From the west, we're going to see a change. Sunny spells will start to break through, bringing with them scattered showers. And when we say scattered, we mean it. Some of these showers could be quite heavy, especially as we head into the evening. So, if you're planning on being out and about, a good waterproof jacket isn't just a suggestion; it's a necessity.

It's going to be a blustery day overall, driven by a fresh to strong and gusty northwest wind. This wind will make those 9 to 13 degree Celsius temperatures feel a good bit cooler than the thermometer might suggest. Later in the day, the wind should start to ease a little, offering a slight reprieve, but don't count on it disappearing entirely.

Tonight: Thunder and Colder Conditions

As Wednesday transitions into night, the unsettled pattern continues. We're looking at scattered outbreaks of thundery rain early on, with the possibility of isolated thunderstorms. These are expected to clear northeastwards as the night wears on.

Following that, drier, clearer, but definitely colder weather will move in. Temperatures are set to drop, with lowest readings between 0 and 7 degrees Celsius. It will be coldest away from the west and southwest coasts, so inland areas should prepare for a chill. The wind will be light, either southwesterly or variable, so at least the biting wind of the day should subside.

Looking Ahead: A Very Unsettled Week

This unsettled theme isn't just a one-day wonder. The national outlook from Met Éireann paints a picture of a very active weather pattern for the rest of the week, with frequent wet and windy spells.

Thursday, October 22: Tomorrow starts off with mostly dry conditions, some sunny spells, and only scattered showers across the west and north. But this calm won't last. Very heavy rain is expected to develop in the southwest during the afternoon, pushing northeastwards into the evening. Localized flooding is a real possibility, especially for those in Munster and Leinster. Light to moderate east to northeast winds will also strengthen later in the day, making for a very wet and windy evening across the southern counties. Temperatures will be a touch milder, ranging from 10 to 14 degrees.

Thursday Night: This is where things could get really interesting. Thursday night is forecast to be extremely wet and windy, with the potential for stormy conditions in some areas. Widespread heavy and persistent rain will affect much of the country, and more flooding is expected. Winds will be cyclonic variable, veering northwest and strengthening further overnight, reaching gale force in places. Lowest temperatures will be between 5 and 8 degrees.

Friday, October 23: The lingering wet and windy weather should clear eastern counties by mid-morning on Friday. The rest of the day will see sunshine and well-scattered blustery showers, mainly affecting western counties. Highest temperatures of 9 to 13 degrees. Fresh and gusty northwest winds will moderate before evening. Friday night looks largely dry and clear initially, but another bout of wet and rather windy weather is expected to move in from the west later. Lowest temperatures will be 3 to 8 degrees, with westerly winds backing southerly and freshening, bringing strong and gusty conditions near south and west coasts.

Saturday, October 24: Saturday will be rather wet and windy early on, with spells of heavy rain, which will then turn more showery through the day. Fresh to strong and gusty south to southwest winds will reach gale force in some Atlantic areas. It's looking humid, with highest temperatures of 12 to 16 degrees, making it mildest across Munster and Leinster. Saturday night will see some thundery showers affecting the north and west, with the odd heavy shower further east. Lowest temperatures of 6 to 9 degrees in a brisk westerly wind.

Sunday, October 25: Sunday is shaping up to be a cool, breezy day with sunshine and showers. Some of these showers could be heavy, particularly in the west and north. Highest temperatures of 9 to 12 degrees in a fresh and gusty westerly wind. Sunday night will be largely dry with clear spells. Keep an eye out for mist and fog forming in light to moderate south to southwest winds. Lowest temperatures of 4 to 8 degrees.

Public Holiday Monday, October 26: And finally, the Public Holiday Monday is expected to be wet and windy. It will also be mild and humid.

Staying Safe and Prepared

With such an active weather forecast for the coming days, it's always a good idea to stay prepared. Keep an eye on the official forecasts from Met Éireann, especially if you're planning any travel or outdoor activities. A good quality waterproof and layers are going to be your best friends this week.

It's a classic Irish autumn, really. A bit of everything, often all at once. Just remember to embrace the bluster, enjoy the brief sunny spells, and keep that umbrella handy.
