The UK is expected to bake again this weekend on banking holidays with temperatures dropping to 30C (86F).
The headquarters office said parts of south-east England may experience temperatures higher than the normal 15 degrees for this time of year, with the mercury peaking almost on banking day on Monday.
“The average temperature for this time of year is 15 C,” a Met Office spokeswoman said. “Right now, temperatures are 20C (68F) and only over the weekend will get warmer.
“The maximum temperature ever for the end of May for a bank holiday is 32.8 Celsius, which arrived in Horsham, Sussex, on May 29, 1944.”
They said that although it could be approaching, the peak is unlikely to be beaten this weekend.

Saturday’s temperatures in the South will be in the mid-1920s, with London expected to be around 25C, while across the rest of the country it will be slightly cooler, in the low 1920s.
With the wind coming from the northeast, Scotland should sit around the 18C mark at the beginning of the weekend.
In Birmingham, the heat will build from 18C on Friday to 26C on banking, while in Newcastle it will start at around 14C and rise to 20C.
There is a risk of thunderstorms in the bank holiday build-up on Monday, with the Southeast and Southwest expected to be hit, which could end.
This article was amended on May 23, 2018 to remove a reference to a possible “doubling” of the temperature. It is incorrect to say that 30C is twice that of 15C, because the Celsius scale is an interval scale based on freezing and boiling points of water, not an absolute scale, like the Calvin.
