Forget about your winter clothes for the next weeks as the UK is expected to sizzle in an unexpected Indian Summer until the middle of October.  

Parks and seafronts are already busy this weekend as Brits enjoy the 21C temperatures after Tropical Storm Henri’s washouts.

The Met Office has said showers on Monday and Tuesday would be followed by 20C sunshine on Wednesday in preparation for the warm blast next weekend.

Next Saturday starts a three-week spell of ‘prolonged’ sunshine and dry skies as high pressure ‘dominates’ until the second half of October.

British Weather Services senior meteorologist Jim Dale said: ‘Just when you thought summer was all over, an Indian Summer is incoming.

‘For 10 days and likely more, virtually all parts of the UK can expect an extended run of fine, dry, sunny and warmer-than-average weather.

‘Temperatures are set to rise even further to 23-25C in parts towards the end of the month. 

‘There should be some fabulous days to come.’
