In meteorological terms, 1 June is the beginning of Summer in the northern hemisphere.



Meteorologists define northern Summer as the months of June, July and August; but many consider that Summer starts at the Summer Solstice - 1554 UTC (~GMT) on 21 June, when the Sun reaches its most northerly latitude of 23º 26.1’.

The Sun will leave the northern hemisphere at the Autumnal Equinox - 0750 UTC on 23 September, when it returns to the southern hemisphere.

And British Summer Time (BST) will cease at 0100 UTC on 27 October, in compliance with an EU directive since 2002, which states that ‘Summer Time’ will be observed between the last Sundays in March and October, clocks to change at 0100 UTC.
