Ireland’s Weather Forecast: Thursday 27 August
As Thursday, August 27th, begins, Ireland's weather map shows a bit of everything. Many will start the morning dry, but don't get too comfortable. Rain is expected to spread throughout the day, particularly across eastern, southern, and midland regions. It won't just be a light drizzle; Met Éireann warns it could get heavy at times, bringing the chance of thunderstorms and even some surface flooding. So, if you're out today, especially in those areas, an umbrella and waterproof shoes are probably a good idea.

I always get a little nervous when I hear "potential for surface flooding." It's one of those phrases that makes me double-check my commute or rethink an afternoon walk. The unpredictability of these summer thunderstorms, even in late August, means you could go from sunshine to a downpour in minutes. We've certainly seen our share of sudden weather shifts this year.
For those in the west and northwest, you might catch a break. It looks drier and warmer there, with some welcome sunny spells. However, even these regions aren't entirely safe, with isolated showers and thunderstorms still possible later in the day. Temperatures across the country will range from 18 to 24 degrees, with mostly light northeasterly breezes. That's a decent range, but the humidity that often comes with thundery conditions can make even 20 degrees feel a bit muggy.
What to Expect Through the Day
The morning will really set the tone. If you're in Dublin, Cork, or anywhere in the midlands, be ready for that rain to move in. It's the kind of day where you might want to consider indoor activities or make sure your plans aren't too weather-dependent. For those on the west coast, say in Galway or Donegal, you're likely to see more sunshine, at least initially. Enjoy it while it lasts, as those isolated showers can sneak up on you.
I always find it fascinating how quickly the weather can change across such a relatively small island. One minute you're basking in sunshine, the next you're dodging puddles. It's part of the charm, I suppose, but it certainly keeps you on your toes when planning anything outdoors.
Looking Ahead to Tonight
Tonight, the rain is expected to continue over the south, east, and midlands. Again, heavy downpours are possible, and thunder isn't out of the question. For the west and northwest, it will be a drier night, with only a few scattered showers. The good news is that the rain should gradually ease overnight and start clearing eastwards by morning.
Temperatures tonight will dip to between 13 and 16 degrees. With light northwesterly or variable breezes, we could see patches of mist and fog forming, especially in sheltered areas. This is pretty typical for late August nights, so be mindful if you're driving early tomorrow morning.
Friday's Outlook: A Glimmer of Hope?
As we look towards Friday, August 28th, a more optimistic picture emerges. Any lingering mist, fog, or rain in the east should clear through the morning. Most of the country is then set for a brighter day, with sunny spells and scattered showers.
Temperatures on Friday will be between 18 and 23 degrees, with the coolest conditions expected in the northwest. Light, occasionally moderate, northwest breezes will be the order of the day. So, while we're not entirely free of showers, it does sound like a more pleasant day overall compared to Thursday's potential deluge. It's the kind of weather that makes you think about getting out for a walk, maybe even a coastal one if you're lucky enough to live near the sea.
The Weekend and Beyond: Staying Unsettled
Unfortunately, the longer-range forecast suggests this unsettled pattern isn't going anywhere fast. Friday night will start dry for most, but rain will move in from the southwest, gradually extending across much of the country. Northern areas might stay dry, though.
Saturday looks like a wet start for most, with rain continuing before gradually clearing eastwards through the morning and early afternoon. Drier, brighter weather should follow, with temperatures ranging from 16 to 21 degrees. Saturday night will be mostly dry with clear spells, but more rain and showers are expected to move in from the west towards morning.
Sunday brings more widespread rain, potentially heavy with thunderstorms, and a noticeable drop in temperature, with highs of only 16 to 19 degrees. Monday will be breezy with showers, and temperatures remaining in the mid to high teens. The outlook for Tuesday and Wednesday next week suggests a continuation of unsettled conditions, with further rain and showers.
It seems we're firmly in that late-summer, early-autumn transition period where the weather can't quite make up its mind. While we've had some lovely spells this summer, this unsettled pattern reminds us that we're heading into the wetter months. It's a good time to make the most of any dry spells and keep an eye on the forecast from official sources like Met Éireann (https://www.met.ie) if you have outdoor plans.
So, for today, embrace the mixed conditions, stay safe if you're in an area prone to heavy rain, and keep an eye out for those sunny breaks. And for those in the west and northwest, enjoy the slightly better weather while it lasts!
