Ireland's Hottest Day Ever

☀️ Ireland's Hottest Day Ever? What This Week's Record-Breaking Heat Means for Your Garden

Posted: 25 June 2026

It's official — Ireland is sizzling. As you read this, meteorologists at Met Éireann are watching the thermometers closely, because today could go down in the history books.

Ireland's all-time high temperature record stands at 33.3°C, set way back at Kilkenny Castle on 26 June 1887 — and that 139-year-old record is under serious threat today, with temperatures of 33°C forecast in parts of Mayo and Roscommon. Meanwhile, the Status Yellow high temperature warning in place since Tuesday has been extended all the way to Saturday morning, with Met Éireann warning of intense heat, humidity, and possible "tropical nights" ahead.

To put that in perspective: a typical June day in Ireland sees average temperatures of between 16 and 19 degrees. Right now, we're nearly double that. Ireland, it seems, has temporarily relocated to the Mediterranean. TheJournal.ie

A Week Ireland Won't Forget

Yesterday saw a high of 27.5°C at Moore Park in Co. Cork and 27.1°C at Oak Park in Co. Carlow — balmy by anyone's standards. But today is shaping up to be the real headline act. Met Éireann has forecast highs of between 25 and 31°C, with temperatures possibly climbing higher still in parts of the midlands and west. RTÉTheJournal.ie

And it's not just Ireland. The UK logged its highest temperature for June, reaching 36.1°C in southern England, while France recorded its hottest day since records began, with temperatures peaking at 44.3°C in the southwestern town of Pissos on Monday. A heat dome has settled over Western Europe, and Ireland is getting a taste of it. RTÉ

So… What Do You Do With Weather Like This?

Well, if you're an Irish person staring out the window at actual, genuine sunshine — you do what comes naturally. You go outside.

And if you go outside on a day like today, there's really only one thing to do: fire up the BBQ.

Think about it. You've got the longest evenings of the year. The garden is warm — actually warm. The neighbours are out. This is the moment that all those optimistic purchases of charcoal and marinade have been leading to.

Whether you're a gas grill convert or a loyal charcoal devotee, this is your week. A slow cook in 30-degree heat, a cold drink in hand, and nowhere else to be — there are worse ways to mark a piece of Irish history.

If you're looking to make the most of the sunshine and haven't yet got your outdoor setup sorted — or you're thinking about upgrading — we've got you covered over at TheOrphanGirl.ie. From gas and charcoal BBQ reviews to accessories, garden furniture, and everything in between, it's all there to help you make the most of days like these.

A Few Sensible Reminders

Of course, record heat in Ireland also means taking a few precautions:

Met Éireann has flagged that the high temperatures will increase the risk of thunderstorms developing — Thursday is expected to see some in the northwest, so keep an eye on the forecast before you commit to an evening outdoors. Met Éireann

If you're using a BBQ, make sure to thoroughly soak the embers after use and confirm they're fully extinguished — fire risk is elevated in conditions like these. Met Éireann

And stay hydrated. Drink water. Check on elderly neighbours. The usual Irish advice applies, just with the added novelty of it actually being necessary.

Enjoy It While It Lasts

Saturday is forecast to bring cloud and rain, with temperatures falling back to between 17 and 23 degrees. By Sunday, highs are expected to drop to around 15 degrees in the west. Typical Ireland, right on schedule. TheJournal.ie

So today and tomorrow are your window. The record books may be rewritten before the weekend is out — and if they are, you'll want to be able to say you were out in it, tongs in hand, making the most of the most extraordinary Irish summer in living memory.
