Much of Britain suffered the coldest summer for almost two decades, Met Office statistics show.
As Britons return to work today after a soggy Bank Holiday weekend, official weather data reveals that average temperatures were significantly down on recent years.
The UK’s average temperature from June 1 to August 15 was only 57F (13.9C) – the lowest for 13 years.
For central England the average was 59F (15C), making it the coolest summer since 1993.
Helen Waite, a Met Office forecaster, said: “The average temperature for central England this summer has been just 15C – this sort of temperature is normally typical of September.
“Generally speaking, you would expect to see temperatures of at least 17C for this time of year.”
