UK Heatwave Breaks as Heavy Rain and Cooler Air Move In

After a scorcher of a weekend that pushed Scotland, Wales and Northern Ireland to their hottest day of the year, the UK’s third heatwave of 2025 is now giving way to grey skies and heavy downpours — and for many, that’s frankly a bit of a relief.

Temperatures Tumble After 33C Highs

Saturday saw temperatures spike to a blistering 33 degrees in some areas, with crowds at outdoor events like Glasgow’s TRNSMT festival being sprayed down with water to stay cool.
In parts of Wales and Northern Ireland, families flocked to beaches and parks, trying to make the most of the hot spell before the inevitable switch.

One-liner: That switch came right on cue — the Met Office says the mercury is dipping fast.

Most regions can expect a drop back into the teens and low twenties. It’s not exactly chilly, but after days of sweaty toss-and-turn nights, many are ready to swap fans for blankets again.

UK summer rain after heatwave forecast

Wet Weather Sweeps Across the UK

With the cooler air comes a fresh batch of heavy rain.
Forecasters warned that Sunday night into Monday would bring widespread showers across Scotland, Northern Ireland, Wales, and much of England too.

One quick note: Some parts will see localised downpours heavy enough to cause surface water and tricky driving conditions.

This is typical British summer — a sizzling high one day, a soggy school run the next.

People Split Over the Big Cool Down

While plenty of sunseekers hate to see the back of a heatwave, there’s been no shortage of sighs of relief.
The elderly, families with young kids, and folks working outdoors have all had their struggles in the sticky heat.

One-sentence para: The change means a better night’s sleep for many.

There’s a real split, though — with BBQ diehards and festival-goers already hoping the sun makes another appearance before summer’s out.

Met Office Watching What’s Next

Forecasters are keeping a close eye on how the jet stream behaves over the coming days.
The general outlook? More unsettled weather, with sunny spells fighting it out against showers.

One-liner: Don’t pack the umbrella away just yet.

While there’s no immediate sign of another intense heatwave this month, longer-term projections suggest these temperature spikes will keep coming as the UK’s “new normal” summer becomes more unpredictable.

What Should You Do Now?

If you’ve been wilting in the heat, the advice is simple:

  • Keep an eye on local flood warnings if you’re in a downpour zone.

  • Watch out for slippery roads and sudden spray when driving.

  • Remember that cooler doesn’t mean cold — layers are your friend.

  • And, of course, enjoy the breather from all that sunburn and sticky nights.

One short line: For now, the heat is taking a back seat — but in this country, you know it never stays away for long.
