Ireland Weather Forecast: Friday 21 August 2026

It's Friday morning, and the weather, as usual, is a big topic. Whether you're seeing sunshine or a few raindrops outside, you're probably close to what Met Éireann predicts for today. This Ireland weather forecast has what you need.

Today, Friday, August 21, 2026, looks like a typical Irish mixed bag. We'll see a good mix of sunny spells and scattered showers. These won't be everywhere at once, which is good for some, not so much for others. The showers will start mainly in the north and west, which isn't surprising given our usual winds. As morning turns to afternoon, these showers will spread across most of the country. So, if you're out and about, a light rain jacket in your bag might be a good idea.

The good news, for those who prefer a dry evening, is that these showers should fade from the north as the day ends. By the time you're winding down, hopefully, the skies will be clearer.

Temperatures will be fairly mild today, but with a noticeable difference depending on where you are. Highs will range from 13 to 19 degrees Celsius. The cooler end of that range will be in the northwest, while the south can expect the warmest conditions. This difference is pretty normal, driven by a light to moderate northwesterly breeze.

What to Expect Tonight

Once daylight fades, any remaining showers, mostly in the south, should clear early. This will leave most areas with a dry night. We'll see a mix of cloud and clear spells, offering a good chance to see stars if you're away from city lights. It might not be completely shower-free everywhere, though. A few isolated light showers could linger in the north and west, but nothing major.

Overnight temperatures are set to drop to between 6 and 10 degrees Celsius. This is a comfortable range for late August, cool enough for a light duvet. The breeze will stay light, coming from a northwesterly or variable direction, so it won't add much wind chill.

Looking Ahead: The Weekend and Beyond

For those already planning weekend activities, here's a look at what Saturday and Sunday have in store. The general outlook is positive for the weekend and into Monday, with mostly dry weather and some sunshine. However, things are expected to become a bit more unsettled mid-week, with showers or more persistent rain returning.

Saturday 22 August

Tomorrow, Saturday, looks mostly dry with plenty of sunny spells. Always a welcome sight for a Saturday. There's just a small chance of a light shower in the west and north, so if you're in those areas, keep an eye on the sky, but don't let it spoil your plans.

Temperatures on Saturday will generally be between 15 and 20 degrees Celsius. Again, the south will be warmest, with the northwest a bit cooler. A light northerly breeze will be present, making for pleasant conditions overall.

Saturday night will be dry for most, with clear spells. However, the northwest might see more cloud and a slight chance of a light shower. We might also see some mist and fog patches develop as the night goes on, especially in sheltered areas. Lowest temperatures will be similar to Friday night, ranging from 6 to 10 degrees, with calm or light variable breezes.

Sunday 23 August

Sunday morning will start with any mist and fog clearing. This will lead into a mostly dry day with sunny spells. There's still that slight chance of an odd light shower, but nothing that should disrupt your plans too much. Highs will be between 16 and 20 degrees Celsius, with light southerly or variable breezes. A perfect day for getting out and enjoying the last of the summer weather, maybe a walk along one of Ireland's beautiful coastlines, or a visit to a local market.

Sunday night looks dry with long clear spells. This means those mist and fog patches might return in the calm conditions. Temperatures will be a touch milder, between 7 and 11 degrees.

Monday 24 August

Monday looks dry and bright for most of the day, a nice start to the week. However, the evening might bring some cloud and potentially some showers moving up from the south. This day will be warmer than the weekend, with highs between 18 and 22 degrees Celsius, accompanied by a light to moderate southeasterly breeze.

Tuesday 25 August

Current indications for Tuesday suggest quite a bit of cloud, with showers or more persistent rain moving up from the south. Some of these could be heavy, or even thundery, so it looks like the settled spell will be ending. Highs are expected to be between 17 and 21 degrees, with moderate southeast to east winds.

Further Outlook

The general outlook for the days after Tuesday is for continued unsettled weather, with showers or more persistent rain. So, make the most of the relatively dry and sunny conditions this weekend and early next week, because it looks like more typical Irish weather is coming back.
