Spring 2026 - General Discussion

Valentia 29.2C @ 13:00

Thunderstorm warning issued for the S and SW for 2 hrs, beginning now. Downpours and hail damage expected.

Big juicy clump of cells about to make landfall all along the Cork coast. I would expect some flash flooding from inundated drains in the city.

I’m seeing purple on the Netweather radar (purple rain!) for the first time ever which means intensity of 200mm per hour, take care in Cork,

Lots of rumbling, a few flashes and some spits of rain in cork harbour.

Welsh blob looks good on Satellite too

That station is right on the North coast though. It’s almost on a mini peninsula I think so it’s almost surrounded by the cool sea. It wouldn’t really be representative of temps in the wider area. If you went even just 200 or 300 metres inland yesterday the temperature was probably a few degrees higher.

That’s not to say it’s a badly located station like Shannon for example. In fact, it’s well away from any man-made buildings and concrete so it’s great for comparing historical records.

But anytime there’s a stiff North sea breeze on a warm day, temperatures there will struggle to get past the maximum temperature of the sea which is around 13° in late May and 15° or 16° in summer.

Yes, I too left the house today in shorts and a t-shirt only and any exposure to the breeze was unpleasant. But, despite my life on this island my body yearns for big heat so I know it's different for everyone, before I offend anyone who thinks it's roasting! 😁

But it's all swings and roundabouts. We can look on during the hot spells of the more intense heat further inland, but in the Westerly dominated weather patterns that frequent us in Summer, we can still get some decent sun and temps of 18-22c in Dublin while the western half of the country really struggles in the mid-teens. So it's easier to take the sea breeze on the chin knowing generally we will do so much better across the entire summer here on the East coast.

27C at Belmullet at 2pm is impressive. What's it's record?

Belmullet 28C at 3pm. Anyone know it's record?

I wasn't talking about the 19th century, I was talking about the increase in average temperatures since the 1990's, which in turn were increased from the previous 30-year period.
