When will it rain in London? Major weather change predicted after long heatwave

The heat goes on. London has basked in eight days of heatwave conditions with daily temperature highs above 28C since Sunday, July 5.

The third heatwave since May has seen the thermometer reach 34C in the capital and continued a long spell of dry weather stretching back 16 days to June 27.

The hot and dry weather has fuelled the spread of two fires in London in the past three days that have caused major disruption to the capital.

London Fire Brigade is warning of an “extreme” risk of wildfires in the capital today (Monday), as the city basks in another warm day of largely unbroken sunshine.

With parks and gardens turned into tinder boxes - and the threat of a widespread London hosepipe ban seemingly growing by the day - the question people will be asking is: When is it going to rain again?

What’s the forecast for this week?

Monday looks set to be dry and warm, with temperatures reaching around 27C according to the Met Office.

That would signal an end to the current heatwave in the capital, which is defined as at least three straight days of highs of at least 28C.

However, it’s set to get hotter again on Tuesday with a predicted high of 31C. The rest of the week also looks warm and dry, with daytime temperature peaks of 30C on Wednesday, 29C on Thursday and 27C on Friday.

Is there a change in the weather coming?

While the Met Office sees little change to the drought-like conditions in it’s seven-day forecast for London, BBC Weather is forecasting a 50% likelihood of rain through much of both Friday and Saturday afternoon.

After that, it is forecasting a return to mainly dry and sunny weather with highs of between 27C and 29C between Sunday, July 19 and Friday, July 24.

Thunderstorms on the horizon?

At the time of writing (11.4am on Monday, July 13), BBC Weather was predicting thunderstorms for London on Saturday, July 25, giving a likelihood of up to 60% of that happening at 60%.

It comes after two spectacular waves of thunderstorms hit London on June 27 and June 23, causing thousands of lightning strikes and flash flooding.
