After a fortnight of unsettled weather, forecasters have predicted a return of summer for the start of September with temperatures reaching up to 25C in the south of England.
A Met Office spokeswoman told the Daily Mail: "We could see temperatures hit 22C to 24C at Heathrow on Sunday with highs in the 20s across the south and late teens in the north.
"Wednesday will be very warm in the south, we are looking at up to 25C – but there might be some thundery outbreaks on Thursday."
She added that most places will remain dry, sunny and warm until Friday and Saturday.
Forecaster Leon Brown at The Weather Channel tells AOL Travel that the weather next week will be cloudier over the south on Monday as a weak front moves southwards.
He said: "There is likely to be some light rain too, but petering out and clearing from the west in the afternoon. The best of the sunshine will be in the north over south and east Scotland. Temperatures will be a warm 20C to 22C in the south.
"It is expected to be still quite cloudy over eastern England and the East Midlands on Tuesday, with the best of the sunshine over the north and west. More sunshine on Wednesday and Thursday, but beware some dense morning fog in the Midlands and East England on Thursday. Temperatures will be widely in the low 20Cs in the afternoons."
