The hottest day ever in the UK was actually even warmer than first thought - and peaked a few miles away from the town given the accolade.
Gravesend spent seven weeks thinking it was hottest
Gravesend in Kent recorded a high of 38.1C (100.6F) on 10 August, which had been acknowledged as a new UK record.
But it emerged on Tuesday that a temperature of 38.5C (101.3F) was recorded elsewhere in Kent on the same day - in Brogdale, near Faversham.
The Met Office said the new record had only been announced seven weeks later because results from Brogdale were only checked monthly.
Sunniest September on record
A spokeswoman said: "Gravesend is a real time observation station so we get their results every day, hence why we could announce it was the hottest place.
"In Faversham, the results come in every month.
"We had to go and verify the information at Faversham to check the equipment and check it was running correctly.
"That weather station is not run by the Met Office but by a volunteer so we had to check it ourselves and release the result now."
The Met Office also revealed on Tuesday that this month had been the sunniest September since records began in 1961, with bright sunshine for an average of six hours a day across the UK.
September also saw 58% less rain than the average and average temperatures 0.9C above the norm.
