Temperatures are expected to rocket to 35C next month, just short of the blistering 38.7C which smashed the record books in Cambridge on “Furnace Thursday”.
This weekend’s washout will be a distant memory as a plume of hot air is predicted to sweep Britain from as early as Wednesday.
The Weather Outlook forecaster Brian Gaze said: “Summer’s gone AWOL, with a miserable few days for families on holidays.
“But the heat will be back later in the week and again in mid-month, when 35C is possible.”
“After the past week’s extreme heat, three more are forecast in Britain this summer as air from Africa arrives.”

It comes after the Met Office issued a yellow weather warning for almost all of England, Scotland and Wales, as thunderstorms lashed the country, sparking flood alerts.
The mercury dramatically plunged to 15C in Cambridge today, welcome relief for residents who likened the heat earlier in the week to “Death Valley”.
Leon Brown, head of meteorological operations at The Weather Company’s Weather Channel arm, said: “After the past week’s extreme heat, three more are forecast in Britain this summer as air from Africa arrives.
“Each spell would reach at least 28C, 5C hotter than average.
“Next weekend has up to 29C possible locally, then mid-August is forecast a plume with above 30C and up to five days’ heat, and a longer hot spell from the second week of September has a good chance of 30C.”
But more wet weather will arrive on the week beginning August 5, Mr Brown told The Sun.
Rain and clouds are set to dominate in many northern and eastern areas of the country tomorrow although showers will turn light and patchy towards the evening.
Southern and western Britain will be largely dry and clear however northern Scotland will endure heavy downpours, forecasters say.
The start of the week will see sunshine break through the clouds, but thundery showers could also be on the way.
Britain’s scorching heatwave last week was just one level away from sparking a “National Emergency”.
Thousands of Brits stripped off and flocked to the beach to bask in the baking hot sunshine.
