Summer in the UK ends on September 23, so there may be some hope that the season will end with sunny skies.

The UK was not hit by a raging heatwave this summer, in comparison to 2022 when Brits saw highs of 40C.

Brits have instead been met with overcast skies and heavy rainfall for the majority of summer.

Southern Europe, in particular Italy, Greece and Spain saw a deadly heatwave hit the continent, with scorching highs of 50C.

On September 11, temperatures could rise again to 26C, suggesting the heatwave could last for as long as 10 days.

Manchester is set to see 25C and the Scottish Highlands are expected to bask in a pleasant 24C blaze.

According to the Met Office, temperatures are likely to remain close to average for the first 10 days of the month.

“Temperatures are likely to be near average, although increasing slightly in sunnier spells, compared to previous days.

“However, occasional showers or spells of rain are still possible here. Temperatures are most likely to be around average overall.”
