UK Weather: Bank Holiday Heatwave Before Stormy Week Ahead
Britain is set for a burst of late-summer heat on bank holiday Monday, with temperatures expected to climb close to 30C in parts of the country.
But the fine spell will be short-lived, as the remnants of Hurricane Erin are forecast to sweep in, bringing wind, rain and cooler conditions for much of the week.

Sunday will bring highs of 26–27C, before Monday sees London’s Notting Hill Carnival basking in sunshine with temperatures pushing 28–29C.
“Today and tomorrow it will be largely dry across the UK apart from the odd spot of rain across Scotland today. There will be increasing amounts of sunshine and temperatures continuing to climb,” said Met Office meteorologist Craig Snell.
The warm picture is expected to break down later on Monday. “On Monday, it will be a very warm and sunny day for most. It will start to go downhill and rain will start to move in for Northern Ireland into the afternoon,” Snell added.
By Tuesday, cooler air will push across the country, dragging temperatures back to the seasonal norm: low 20s across the south and high teens in the north.
Those making beach plans are being warned to stick to lifeguarded locations, with strong waves expected on Monday and Tuesday. From midweek, showers will become widespread, especially in the west.
“It will be heavy at times in the west, but at the moment we’re not expecting too many impacts, and it may for farmers or anyone who needs the rain be welcome,” Snell said.
Hurricane Erin, which had been a powerful Category 5 storm on the US East Coast, has now weakened to Category 2 as it moves across the Atlantic.
Even so, its remnants will drive the UK’s unsettled outlook, with a band of rain sweeping eastwards on Wednesday and low pressure sticking around into the weekend.
In the US, the storm forced thousands to evacuate in North Carolina and led to more than 60 swimmers being rescued from rip currents at Wrightsville Beach.
While its impact on Britain is expected to be far less severe, the week ahead looks set to be dominated by damp skies, gusty winds and a noticeable drop in temperatures.
For many, this bank holiday will be the last chance to savour summer sunshine before the reality of autumn arrives.
