When looking at daytime temperatures the UK average for the month was 19.9 C, the same average maximum daytime temperature as in the June of the still talked-about summer of 1976, and placing it joint second (in records dating back to 1910) just behind 1940, when 20.6 C was reached.
It has also been a very sunny month and for the UK as a whole, with provisional figures showing it is the 4th sunniest on record behind 1957, 1940 and 1975 (figures dating back to 1929).
It was the fifth sunniest for Northern Ireland and England, third sunniest for Wales and fourth for Scotland."
