After a chilly start to May, forecasters are expecting a mini-heatwave to warm the capital with 22 degree sunshine.
Many areas of the UK will reach 18 degrees due to swathes of hot air from the Atlantic, according to a WXCharts forecast.
Early predictions suggest temperatures will climb further, reaching a delightful 22 degrees in parts of the South East by Saturday, May 22.
The sunshine will present a warm welcome to those planning to hit the road and take advantage of the grand reopening of hotels, hostels and B&Bs in England.
It suggests Brits could quite literally be headed for ‘brighter times’ in line with further easing of Covid-19 restrictions on May 17.
However, the Met Office said it is not seeing any significant change or trends towards much warmer conditions with temperatures predicted close to or just below average.
Spokesperson Grahame Madge said: “We think that the most likely scenario is that we will continue with unsettled weather really until the month’s end.
“You would expect the conditions to be warmer at the end of the month as we get further through spring.
“Normally to get quite a rise in temperature, you need one of two things. You need clear fine weather or an incursion of warm air being swept up from further south in Europe but we are not getting that at the moment.”
In the meantime, the wet and windy weather is set to continue across England this week with further thunderstorms and torrential downpours expected nationwide.
The capital will remain cloudy with showers anticipated on most days and the occasional afternoon downpour.
Throughout the week, temperatures will fall from highs of 18 degrees on Wednesday to highs of around 14 degrees by Saturday.
Londoners should wrap up before heading outdoors, with more rain expected on Saturday and thundery showers on Sunday.
It means, unfortunately, foodies and pub goers might not get to enjoy a dry beer garden or terrace during the last weekend before indoor venues reopen.
A Met Office spokesperson said: “Some more persistent rain on Saturday morning. Temperatures remaining below average.
“It will most likely be remaining unsettled throughout the period, with Sunday seeing sunny spells and thundery showers.”
In the UK, the north will perhaps see the best of any settled weather while the south is most likely to be drizzled with long rainy spells.
Mist and cloud might also remain along the coast in northeast England and eastern Scotland, according to the Met Office.
Its forecast states: “It’s likely to be breezy at times, especially around coastal areas in the south and west of the country.
“Temperatures will be near to or slightly below average, with the best of any warmer spells in the southeast, and with the formation of any overnight frosts becoming less likely.”
