Irish Bank Holiday weekend set to shine as storms clear mid-week

The bank holiday continues to look positive
Weather expert Alan O'Reilly's assessment of conditions expected for the long weekend ahead.

Why does Wednesday matter so much? It seems like just another day in the forecast.

Mimi

Wednesday is the hinge. That's when the system causing all the rain and thunder finally moves off. The afternoon is when you actually see the sky again—sunny spells, not just breaks between showers. It's the turning point.

Mark

So the weekend itself should be decent, then?

Mimi

That's the idea. The clearing that starts Wednesday should hold through Friday and into the bank holiday. Not perfect—there might be a shower here or there—but genuinely dry and sunny in stretches. After what people have been dealing with, that's a big deal.

What about the northeast? The forecast mentions heavy thundery downpours there on Tuesday.

Mimi

That's the worst of it. Tuesday is rough for that region especially. Heavy rain, the possibility of flooding. But even that clears by Wednesday morning. The whole system is moving through, not stalling.

Is this forecast solid, or could it change?

Met Eireann and the independent forecasters are aligned on the broad strokes—wet early week, clearing midweek, drier weekend. That kind of agreement gives you confidence. But weather is weather. A day or two out, things can shift. But the direction is clear.

  • Heavy downpours, lightning, and spot flooding are making Sunday evening and Monday morning genuinely hazardous, particularly across Leinster and the northeast.
  • Tuesday delivers the sharpest blow — thundery, persistent rain that tests patience and infrastructure before finally beginning to scatter overnight.
  • Wednesday afternoon marks the turning point, as cloud cover breaks apart and sunny spells emerge, signalling the end of the unsettled spell.
  • Thursday and Friday consolidate the improvement, offering dry conditions and generous sunshine across the east and south with temperatures climbing to 15–18°C.
  • The bank holiday weekend itself is shaping up as the best stretch of the entire week, transforming outdoor plans from wishful thinking into genuine possibility.

Ireland, long accustomed to the capriciousness of its skies, finds itself on the cusp of a seasonal reprieve. A turbulent stretch of thunderstorms and heavy rain — bearing down hardest on Leinster and the northeast through Tuesday — is forecast to yield by midweek, giving way to the kind of dry, sun-touched days that make a bank holiday feel like a gift rather than a gamble. Met Éireann and independent forecasters align in their optimism: the June Bank Holiday weekend, so often a hostage to Atlantic weather, appears poised to reward those who have waited.

Ireland's weather is about to turn a corner — and the timing could hardly matter more. After a bruising run of rain, thunder, and persistent gloom, the forecast is brightening just as the June Bank Holiday approaches.

Alan O'Reilly of Carlow Weather offered an encouraging read on Sunday morning, and Met Éireann's own outlook supports him: the shift arrives midweek. Before then, there is weather to endure. Sunday evening brings scattered heavy showers with lightning and flooding risks across Leinster. Monday is grey and damp through the morning before brightening into the afternoon, with temperatures reaching 14 to 17 degrees. Tuesday is the roughest day — heavy, thundery downpours in the northeast — before showers begin to scatter overnight.

Wednesday is the pivot. Morning drizzle lingers, but by afternoon the clouds break and sunny spells take hold. By evening, conditions are genuinely fine. Thursday and Friday follow suit: dry, bright, and pleasant across the east and south, with highs in the mid-teens and only the occasional isolated shower to speak of.

For those with the bank holiday weekend in their sights, the outlook is the most encouraging part. The clearing trend that begins Wednesday is expected to hold, making outdoor plans feel less like a leap of faith and more like something you can actually count on.

Ireland's weather is about to turn a corner. After days of rain, thunder, and the kind of gloom that makes you wonder if summer will ever arrive, the forecast is brightening—and it's arriving just in time for the long weekend.

Alan O'Reilly, who runs Carlow Weather and has built a following for his detailed forecasts, offered an encouraging assessment on Sunday morning: the bank holiday weekend is shaping up well. Met Eireann, the national forecaster, backs him up. The shift comes midweek, around Wednesday, when the weather system currently drenching the country finally moves on.

But first, there's weather to endure. Sunday evening will bring scattered heavy showers, with lightning and spot flooding a real possibility, especially across Leinster. Monday starts gray and damp—patchy rain and drizzle through the morning, though the afternoon should brighten with some sun and scattered showers. Temperatures will reach 14 to 17 degrees. Tuesday is when things get properly rough. The northeast will see heavy, thundery downpours, the kind that make you grateful for a roof. By Tuesday night, the showers begin to scatter, and Wednesday morning arrives with rain and drizzle still lingering, but the afternoon is when the transformation happens. Clouds break apart. Sunny spells emerge. By evening, it's genuinely fine and mostly sunny. Temperatures climb to 15 to 18 degrees.

Thursday and Friday follow the same pattern: dry, with plenty of sunshine, especially in the east and south. Highs stay in the mid-teens, with just the occasional isolated shower. The northwest winds moderate. It's the kind of weather that makes people dust off garden furniture and start thinking about plans.

For those watching the calendar, the bank holiday weekend itself—the days that actually matter for time off—is shaping up to be the best stretch of the week. After a punishing run of wet and stormy conditions, the clearing trend that begins Wednesday should hold through the weekend. It's not a guarantee of wall-to-wall sunshine, but it's a genuine improvement, the kind that makes outdoor plans feel less like wishful thinking and more like something you can actually do.
