Temperatures are predicted to top 30C for the sixth day in a row today in the first time such a run of hot weather has ever been recorded in September.

With the hot conditions predicted to continue throughout Saturday and Sunday, this September will be the warmest on record, the Met Office has predicted.

The last time a heatwave stretched across five days in September was in 1911 and 1929.

It comes after temperatures reached 32.6C in Wisley, Surrey on Thursday. September’s highest daily temperature reading was 35.6C recorded on Sept 2 1906 in South Yorkshire.

This year’s hot spell has led to a 552 per cent surge in people seeking heat exhaustion help, according to the NHS.

Advice issued by the health service includes taking “cool baths”, staying out of the sun from 11am to 3pm and avoiding “excess alcohol.”
