It's Wednesday, June 24th, 2026, and if you're in Ireland, you're probably already noticing a change in the weather. We're in for a seriously warm and humid day across the country, a real taste of summer that's been a bit scarce so far this year. Forget those crisp, cool mornings; today is all about the heat, with temperatures climbing and a general stickiness in the air.

Looking at the Ireland weather forecast for today, I see a clear picture: a day that starts a bit hazy for some, but quickly brightens up. Met Éireann says to expect patches of mist and fog early on, particularly for those further north and west. But don't let that fool you; the sun is coming out. Much of the country will see proper sunny spells develop as the day progresses. The south and southeast, in particular, are getting an early dose of vitamin D.

Now, for the numbers: expect temperatures to hit anywhere between 23 and 28 degrees Celsius. The warmest spots will be in the south, so if you're there, you're in for a treat (or a challenge, depending on how you handle the heat!). These are significant temperatures for us, and it means we need to be thinking about staying hydrated and perhaps finding some shade during the hottest parts of the day. The breezes will be light and variable, which unfortunately means they won't do much to cool things down.

Tonight's Outlook: A Warm, Sticky Night

As Wednesday turns into Thursday, the warmth isn't going anywhere fast. Most areas will stay dry tonight with some clear spells, perfect for a late evening stroll, if you can handle the humidity. However, those in Connacht and Ulster might see a bit more cloud cover and even a few patches of light rain or drizzle. Nothing too dramatic, but worth noting.

The real headline for tonight is the overnight temperatures. We're talking seriously mild. Lowest temperatures will range from 14 to 20 degrees. The south and east will be the warmest, potentially making for a slightly uncomfortable night's sleep if you're not used to it. The northwest will be a few degrees cooler, offering a little respite. Light easterly or variable breezes will continue, doing little to break the warmth.

Looking Ahead to Thursday: More Heat and Thunderstorm Potential

Thursday, June 25th, is set to be another hot and humid day. The pattern of dry weather with good sunshine will generally hold, especially after any early drizzle clears from the northwest. But here's where things get interesting: there's a chance of thunderstorms developing later in the day. This is most likely in the west and northwest, so keep an eye on the sky if you're in those regions.

Temperatures on Thursday are expected to climb even higher, reaching between 25 and 31 degrees. Yes, you read that right – 31 degrees! Some places, particularly across the midlands and west, could even see temperatures exceeding that. We're talking proper heatwave conditions here. East to southeast breezes will be light to moderate, again, not providing much relief from the heat.

The Weekend and Beyond: A Shift in the Air

This spell of very warm and humid weather with potential thunderstorms is set to continue for a while, but there's a shift on the horizon. As we head into the weekend, conditions are expected to turn cooler, with a move towards more changeable weather influenced by the Atlantic.

Thursday night looks set to bring heavy showers and possible thunderstorms, mainly to the west and northwest. These could spread further afield overnight, bringing a risk of spot flooding and frequent lightning. That's a good reminder to check local forecasts if you're planning any outdoor activities. Overnight temperatures will remain very warm, between 17 and 20 degrees for most, with light northerly winds.

Friday will likely see those heavy, possibly thundery, showers persist in the northwest for much of the day. For the rest of the country, it will be mostly dry with plenty of sunshine, though the south will see increasing cloud. Temperatures will still be warm and humid, 22 to 26 degrees, but a bit cooler in the northwest and near the south coast.

Friday night will be another mild and humid one, with some patchy rain developing in parts of the south and west. By Saturday, we're looking at more widespread showery rain moving in from the west, with temperatures dropping to 18 to 23 degrees. And then Sunday? Quite breezy, with a mix of sun and scattered showers, and temperatures cooling further to 16-20 degrees. It sounds like the Atlantic is finally going to assert itself.

So, for today, Wednesday, June 24th, enjoy the heat if you're a fan, but do take precautions. Stay cool, stay hydrated, and perhaps plan your day around the warmest hours. It's a real summer's day for Ireland, even if it's a bit of a temporary one. For more detailed local forecasts, always check the official Met Éireann website.
