UK faces 'week-long' third heatwave, with temperatures set to hit 35°C: How many more are in store this summer?
Barely a week after sweating through one of the hottest Junes ever, the UK’s back under the heat dome — again.
Per the Met Office updates, Britain is headed for its third official heatwave of the summer, with temps expected to soar to 35°C in parts of southern England. This pretty much continues an extreme pattern: a record-smashing heatwave in May, another in June, and now, here we go again. With July just getting started, people everywhere are wondering: how long is this latest scorcher going to last, and are there even more coming before summer ends?
Another heatwave on the way?The Met Office says most of England should brace for an extended run of hot, dry weather, with the highest temperatures locked in over London, the southeast, East Anglia, and pockets of the Midlands. Highs could hit 34–35°C. Even usually cool spots will be way above their normal, though northwest Scotland might pull the weather lottery with some rain.
Now, it looks like this heatwave will stick around for seven days in the south, possibly longer. Nights won’t offer much relief either, especially in the cities, where “tropical nights” are possible (which means temperatures at or above 20°C all night) — so good luck getting any real sleep!
The UK Health Security Agency already issued amber Heat-Health Alerts for much of southern and central England, warning that this kind of heat is risky, especially for older people, young kids, and those with health issues.
Third heatwave this summer: What’s next?This is actually Britain’s third official heatwave in 2026. The first hit unusually early, in late May, peaking at 35.1°C at Kew Gardens — which was a record for May. The second followed in late June, and some places in eastern England broke 37°C, the country’s hottest June ever. Both events triggered travel chaos, school closures, wildfires, and pushed hospitals to the limit.
So why so many heatwaves? Forecasters say another zone of high pressure is pulling hot air from southern Europe (which is also roasting this summer). The general setup keeps bringing these sweltering spells, and many scientists say they’re clearly becoming more frequent and more intense as the climate changes.
Could there be even more extreme heat before summer’s over? The honest answer: no one knows for sure.
Long-term weather forecasting in the UK gets fuzzy past a week or two. But the odds right now are leaning toward more above-average warmth through July and August, with maybe some shorter cooler periods mixed in. That doesn’t guarantee more official heatwaves; the Met Office only calls it a heatwave when temperatures sit above a certain threshold for three days or more (thresholds range from 25°C up north to 28°C in London and the southeast). Bottom line, it’s not hard to hit “heatwave” status these days.
