In the UK we have witnessed a lot of different weather of late, making May one of the wettest so far with April having a period of hot temperatures which pleased people with the easing of some Covid restrictions. So a lot of us are wondering whether summer will officially start soon so we can expect warmer weather.
Well it depends on whether you go by the meteorological seasons or the astronomical point of view. The meteorological is the simpler of the two, splitting the year into four seasons of three month blocks based on the Gregorian calendar.
Meteorological seasons – Northern Hemisphere
The meteorological summer always begins on 1 June and ends on 31 August with autumn starting on 1 September. Meteorologists divide the year into four seasons allowing them to organise climate data better.

The start of summer is a few weeks away if you choose the astronomical point of view as it depends on the date of the summer solstice later in June.
The astronomical start date is based on the position of the sun in relation to the earth. In 2021 the summer solstice falls on Monday 21 June, which is also the longest day of the year. Six months later is the winter solstice also known as the shortest day of the year. The summer solstice can be any date between 20 and 22 June. The astronomical summer lasts until the autumnal equinox which in 2021 is on Wednesday 22 September.
