Sunday's Serene Start: A Look at Ireland's Weather Today

After what feels like a bit of a mixed bag this summer, Sunday, August 23rd, 2026, is shaping up to be a cracker for most of Ireland. If you've been holding out for a proper summer's day, today might just be it. We're looking at clear skies, sunshine, and some genuinely comfortable temperatures across the board. So, if your plans involve anything outdoors, you're in luck.

Let's dive into the details of what Met Éireann is predicting for the day, and then we'll cast our eyes a little further into the week, because, let's be honest, we all want to know what's coming after this lovely spell.

Today: Mostly Dry, Sunny, and Warm

This morning, if you woke up to a bit of a misty or foggy start in your area, don't fret. That's all set to burn off pretty quickly. What we'll be left with is a largely dry and calm day. I think "calm" is the operative word here. No blustery winds to contend with, just a gentle ease to the air.

Expect plenty of sunny spells to break through, making it ideal for whatever you have planned. Whether it's a stroll in the park, a bit of gardening, or just enjoying a coffee outside, the conditions are looking near perfect. The only real exception to this widespread dryness is a very slight chance of an isolated shower in Ulster. So, if you're up north, just keep one eye on the sky, but even then, it's not looking like anything significant.

Temperatures are going to be quite pleasant too. After what might have been a slightly cool start to the morning, we're expecting the mercury to climb to between 17 and 22 degrees Celsius. The warmest spots will definitely be in the southern counties, so if you're down there, you're in for a treat. It's that kind of warmth that feels just right, not too hot, not too cool, just a proper mild summer's day.

Tonight: Clear and Chilly Once More

As the sun sets on what should be a beautiful Sunday, the clear conditions are set to continue into the night. It'll remain dry with plenty of clear spells, which is lovely for stargazing if you're away from the city lights.

However, with those clear skies and light breezes, we're going to see some mist and fog patches developing again. So, if you're driving early on Monday morning, be aware that visibility might be reduced in places. It's also going to be another chilly night, which has been a bit of a theme lately when the skies clear. Lowest temperatures are forecast to drop to between 5 and 9 degrees Celsius. So, if you're planning any late-night activities, you might want to bring a jumper.

Looking Ahead to Monday: More Sunshine, But a Hint of Change

Monday, August 24th, is shaping up to be another largely dry day, carrying on the good vibes from Sunday. We'll still see plenty of sunny spells, which is great news for the start of the working week or if you're still on holidays.

However, there's a subtle shift on the horizon. Scattered light showers are expected to develop in the southwest and west later in the day. Nothing too dramatic, but it's a sign that things might be starting to turn a little. Despite these potential showers, it's going to feel rather warm. Highest temperatures are predicted to hit between 19 and 23 degrees Celsius, with light east to southeast winds. So, Monday is still very much a summer day, even with that slight chance of rain.

The National Outlook: A More Unsettled Week Ahead

Now, for the big picture. If you've been enjoying this settled spell, I'm afraid to say that the general outlook for the rest of next week is pointing towards more unsettled conditions. It seems we're in for a bit of a change, with spells of rain and showers becoming more frequent. Some of these could even turn heavy or thundery, which is not ideal for late August.

Monday Night: Cloudier and Milder

Monday night will see things becoming cloudier overnight. Scattered showers will spread in from the south, though parts of the east and northeast might manage to stay dry. It'll be a milder night compared to Sunday night, with lowest temperatures ranging from 11 to 15 degrees Celsius, thanks to a light to moderate easterly breeze.

Tuesday: Rain Spreading Northwards

Tuesday looks like a mostly cloudy day. We'll start with scattered showers, but as the day progresses, longer spells of rain are expected to spread from the south. Temperatures will be a bit cooler than Monday, with highs of 17 to 21 degrees Celsius, accompanied by moderate easterly winds.

Tuesday Night: Heavy Rain and Thunderstorms Possible

Tuesday night is looking quite wet. Expect mostly cloudy conditions with outbreaks of rain, some of which could be heavy. There's also a chance of isolated thunderstorms. Some clear spells might develop in the southwest towards morning. It will remain mild, with lowest temperatures between 12 and 16 degrees Celsius, in light to moderate east to southeast winds.

Wednesday: Humid with More Showers

Wednesday continues the unsettled theme. Generally cloudy skies are forecast, with showers or longer spells of rain. Again, some of these could be heavy or even thundery. It's also going to feel quite humid, with highest temperatures ranging from 19 to 23 degrees Celsius in light to moderate southeast winds.

Thursday: Dull, Wet, and Humid

Thursday looks like a rather dull and wet day. More showers or longer spells of rain are expected, with the potential for some heavy downpours and isolated thunderstorms. It will be another humid day, with highs between 19 and 22 degrees Celsius, in moderate east to southeast winds.

Further Outlook: Unsettled Friday, Some Improvement for the Weekend

The end of the week, Friday, is expected to remain unsettled, with further heavy rain possible. However, there's a glimmer of hope for the weekend. While there's still a chance of some rain and showers, we might also see longer dry spells developing. So, it's not all doom and gloom, but certainly a shift from the lovely weather we're enjoying today.

Enjoy Today While It Lasts!

So, there you have it. Today, Sunday, August 23rd, is shaping up to be one of those classic Irish summer days we all crave. Make the most of the sunshine and warmth, because the forecast suggests a return to more typical unsettled Irish weather for the week ahead. Keep an eye on the latest updates from Met Éireann for the most accurate local forecasts as the week progresses. For now, go enjoy your Sunday!
