How long will the heatwave last?

The heatwave is predicted to last until the weekend, with temperatures reaching the low to mid-30s from Thursday (11 August) before eventually peaking.

Speaking to BBC News, Met Office meteorologist Tom Morgan predicted the UK would experience a “fairly widespread heatwave”.

He said: “It does look like a prolonged period of dry weather and obviously that’s bad news for southern England where some rain would really be useful now.”

When did the hot weather start?

The hot weather began on 9 August, with temperatures across the UK slowly picking up to the mid or high-20s.

When will the hot weather end?

The last day of the hot weather is expected to be Sunday 14 August.

Temperatures will dramatically drop on Monday 15 August, with thunder and lightning predicted in some regions of the UK.

When is the Met Office weather warning?

The UK Health Security Agency (UKHSA) have issued a heat related weather warning which will be in place from Thursday (11 August) to Saturday (13 August).

The level three heat health alert is the third highest alert available and helps healthcare workers in England prepare for high temperatures.

A level 3 is issued when “the Heat-Health Alert thresholds have been exceeded” and “requires social and healthcare services to target specific actions at high-risk groups”.

The warning will cover much of Southern England, as well as areas of eastern Wales.

Dr Agostinho Sousa, Head of Extreme Events and Health Protection at the UKHSA said: “Temperatures will feel very warm again this week, particularly in southern and central parts of the country.

“We want everyone to enjoy the warm weather safely when it arrives, but remember that heat can have a fast impact on health.

“It’s important to ensure that people who are more vulnerable – elderly people who live alone and people with underlying health conditions – are prepared for coping during the hot weather.

“The most important advice is to ensure they stay hydrated, keep cool and take steps to prevent their homes from overheating.”

Met Office Deputy Chief Meteorologist Dan Rudman said: “Thanks to persistent high pressure over the UK, temperatures will be rising day-on-day through this week and an Extreme heat warning has been issued.

“Temperatures are expected to peak at 35C on Friday and Saturday, or even an isolated 36C on Saturday. Elsewhere will see temperatures widely into the high 20s and low 30s Celsius.

“Coupled with the high daytime temperatures there will be some warm nights, with temperatures expected not to drop below the low 20s Celsius for some areas in the south.”
