Summer is upon us
In meteorological terms, 1 June marks the beginning of Summer in the northern hemisphere.
Summer is defined as the months of June, July and August. Some believe that the Summer solstice, 0424 UTC (~GMT) on 21 June, when the Sun is at its most northerly latitude of 23º 26.1', represents the start of Summer, but this is also known as mid-Summer.
The Sun will move back to the southern hemisphere at the Autumnal equinox - 0802 UTC on 22 September.
And clocks in UK go back to UTC when 'daylight saving time' ends in Europe at 0100 UTC on 29 October.
