Despite the temperature being above average for the first month of summer, there were just 138 hours of sun - making it the seventh dullest June since 1929.
It was also the wettest start to summer since 2012, with an average 101.8mm of rain falling across Britain - 39 per cent more than usual.
The Met Office confirmed it was the 11th wettest June since records began in 1910.
Although no counties broke their own records for rainfall, Aberdeenshire and the South East of England saw twice the average for amount of rain.
Forecaster Alex Burkill said: “It was generally a wet and dull month with high levels of rainfall in localised areas.”
Although not as bad as previously, more damp weather is expected in the north, although conditions should be drier in the south.
