It's Sunday, September 27th, 2026, and if you're in Ireland, you're likely waking up to the sound of rain. We're starting the day with proper Irish weather: widespread rain, looking particularly heavy and possibly thundery in places. If you're in the south, prepare for the heaviest downpours, with a chance of localized flooding. It's not exactly the bright, crisp autumn morning we might hope for.

But don't despair just yet. This is Ireland, and the weather rarely stays the same for long. A clearance is on its way, bringing welcome sunny spells. This change begins in the southwest early this morning and is set to sweep across the country, reaching the northeast by early afternoon. So, while you might need an umbrella for your morning walk, you could easily be enjoying some sunshine with your lunch.

After the main band of rain passes, we'll see scattered showers. These will be mostly isolated, but a few could turn heavy later in the day, especially for those in the north and northwest. If you're planning to be out, keep an eye on the sky and perhaps pack a light rain jacket, just in case.

Winds and Temperatures

Wind conditions are a bit mixed this morning. We'll have mostly moderate to fresh and gusty south to southeast winds for a while. Near the southern and eastern coasts, expect strong winds. In the southwest, it starts with more variable, cyclonic, light to moderate winds before shifting to moderate to fresh westerly winds as the rain clears. These westerly winds could strengthen, becoming strong at times in coastal parts of the northwest and west, but they should ease by evening.

Temperatures feel fairly mild for late September. We're looking at highs ranging from 14 to 18 degrees today. Not bad at all, especially once the sun breaks through.

Tonight's Outlook

Tonight brings a much drier picture for most of us. We can expect plenty of dry weather with clear spells. There will still be some scattered showers, mainly further west, but nothing like the widespread rain we're seeing this morning. Temperatures will drop, with lows ranging from 5 to 10 degrees. Winds will become mostly light southerly, though they'll remain moderate near western and northwestern coasts. So, a decent evening and night ahead, perfect for stargazing if the clouds stay away.

What's in Store for Monday?

Looking ahead to Monday, September 28th, it's shaping up to be a much brighter day. We're expecting mostly dry and bright conditions with long spells of sunshine. The sun might turn a bit hazy at times, and there's always a chance of a few isolated showers, but overall, it's a positive outlook. Highs will again be between 14 and 18 degrees. Winds will be mostly light to moderate southerly, backing southeasterly and freshening in western and southwestern coastal parts later in the day. A lovely start to the working week, by the looks of it.

The Week Ahead: Typical Irish Weather

Now, let's look further into the week. The general overview suggests a changeable pattern, which is normal for this time of year in Ireland.

Monday Night: Much of the night will be largely dry with some clear spells. However, it will become increasingly cloudy further south, with rain moving into southern counties later in the night. Lows will be on the milder side, ranging from 9 to 14 degrees, with southeasterly winds freshening.

Tuesday: Get ready for another wet and windy day on Tuesday. Rain will become widespread from the south, and some of it could be heavy and thundery, with localized flooding possible, especially further south. It's looking like a mild and humid day, with highs between 17 and 20 degrees. Southeasterly winds will increase to fresh to strong and gusty, potentially reaching near gale to gale force in some coastal parts of the south and west.

Tuesday Night: A clearance will move into southwestern parts on Tuesday evening or early Tuesday night and extend northeastwards to all areas. The last of the rain should clear from the northeast around midnight or soon after. However, some heavy, thundery, blustery showers will follow overnight, particularly into the south and west. Lows will be 10 to 14 degrees in fresh to strong and gusty southeasterly winds, veering southerly and decreasing moderate to fresh over land, but remaining stronger in many coastal parts and reaching gale force in some western coastal areas.

Wednesday: Wednesday will be another rather windy day. We'll see sunny spells interspersed with fairly widespread showers, some of which could be heavy and thundery, with a chance of hail. Highs are forecast to be 15 to 18 degrees in fresh to strong and gusty southerly winds, reaching near gale to gale force in western coastal parts.

Thursday: Things look like they'll calm down a bit by Thursday. It won't be as windy or showery, with spells of sunshine and good dry periods. There will still be scattered showers, especially further west. It's likely to become cloudier later in the day, with rain probably moving into western parts. Highs of 14 to 17 degrees in moderate, occasionally fresh, southwest winds, backing southerly and increasing fresh to strong along the west coast later.

Friday: Any lingering rain in the east and southeast should quickly clear on Friday morning, leaving a bright day with sunny spells and plenty of dry weather. We'll see just some well scattered showers. Highs are expected to be 14 to 18 degrees in mostly moderate southwest winds.

The overall outlook for the rest of the week suggests more mixed conditions, with good spells of dry weather and lighter winds, though it will occasionally be breezy, with some rain or showers around. There's even a chance that it may become more settled during next weekend, which would be a welcome change for many.

For the most up-to-date information, it's always a good idea to check the official forecasts from Met Éireann, Ireland's national meteorological service, directly on their website: https://www.met.ie/. They provide detailed regional breakdowns and warnings that can be incredibly useful when planning your day.

So, there you have it. A wet start to Sunday, but with brighter spells on the way and a mixed bag for the week ahead. That's typical Irish weather for you – always keeping us on our toes! Enjoy your Sunday, whatever the weather brings your way.
