Thursday looks set to be the hottest day of the year so far, with a peak temperature of 32.6C recorded in Wisley in Surrey, the Met Office said.
It comes as this week’s heatwave broke the record for the most consecutive days with temperatures above 30C in September.
The Met Office said in a post on X, formerly known as Twitter: “After getting very close yesterday, today is provisionally the hottest day of the year so far, with 32.6°C recorded in Wisley.”
Thursday was the fourth day with temperatures above 30C recorded in the UK, with high temperatures expected to continue through the weekend, peaking as high as 33C on Saturday.
Stephen Dixon of the Met Office said temperatures above 30C in September are uncommon but not unheard of, however the length of this current heatwave is unusual.
The highest ever September temperature was 35.6C, recorded in 1906.
Clear and settled conditions have also given rise to glowing sunsets and hazy dawns as dust from the Sahara is blowing north in the atmosphere.
What is the forecast for the rest of August?
Temperatures are expected to return closer to average for this time of the year from next week, with more changeable conditions expected, particularly in the north.
According to The Met Office there are indications that late September into early October could see the weather be drier than normal due to a higher probability of high pressure.
The Met Office also said there are “stronger indications” that temperatures may be above average for the time of year, with more “unseasonably warm spells” expected.
