Temperatures are set to reach sizzling highs again today as even residents in Scotland's Highlands enjoy scorching sun.
With a high of 30C (86F) expected in the south of England and possibly 28C (82F) in Scotland, Britons will be bathing in warmer climes than parts of Portugal and Spain.
Yesterday's high of 29.9C (85F) in Solent, Hampshire could be beaten, according to the Met Office, which predicted highs will continue until the weekend.
The hot weather brings with it a risk of heavy downpours though, warned forecaster Emma Corrigan, who said rain could hit the south west this week.
"There is a risk of isolated heavy thunderstorms in the south west on Wednesday and Thursday and perhaps into Friday," she said.
"The storms could be quite slow-moving and therefore heavy in places."
No weather warnings have been issued ahead of the expected rainfall, she added.
After a hot and humid July, August, while expected to begin with some fine and dry weather, could see lower temperatures as a "frontal feature" pushes in from the south east.
Billy Payne, a forecaster with Meteogroup, said August "should get off to a fairly dry and settled start" with a build-up of high pressure.
He said next week will bring a slight drop in temperatures but still possible highs of 23C (73F) in the south of England on Monday.
