Currently, the Met Office says the August heatwave will not match the intensity of the July heatwave.

“There will be plenty of sunshine for the vast majority of the UK and temperatures are rising by the day,” forecaster Tom Morgan said.

“Not everyone will see these sunny conditions initially but towards the end of the week even Scotland and Northern Ireland will join the rest of the UK in generally nice, sunny and very warm if not hot conditions.

“It looks like an extended dry spell and that is obviously bad news for southern England where some rain would really come in handy now.

“In terms of temperatures we are looking into the low to mid 30s from Thursday so a fairly widespread heatwave is developing across the UK this week.

“The peak in temperatures will likely occur on Friday or Saturday.”

The hot weather is being caused by an Atlantic anticyclone — a different system than the one that caused the July heatwave.

Last month’s extreme temperatures resulted from a “heat dome” moving north from North Africa before settling over southern Europe.

The Met Office has also said it is unlikely to match July’s heatwave as the sun is less powerful in August – it’s lower in the sky and daylight hours are marginally shorter.

A big unknown is how long this heatwave will last, with the Met Office forecasting it could last into mid-August.

Over the weekend, the Essex County Fire and Rescue Service said around 40 people were forced to evacuate properties as a result of a fire that damaged more than a dozen homes.

It had started as a garden fire.

“While summer weather normally provides the perfect opportunity for an evening BBQ or gathering around a fireplace, we strongly discourage people from making fires at this time,” said Neil Fenwick, Essex area manager.

The 40℃ temperatures observed this week currently occur every 100 to 300 years, but could occur as frequently as every 15 years by 2100.
