Although the seasonal differences in Britain are not as extreme as in some countries, there is still a large difference between winter and summer. The year is split into four seasons roughly each 3 months long, though the weather in Britain can be very erratic and so the seasons often overlap or don’t follow the standard pattern. Below you can find the general weather conditions of each season in England. All the stats are based on Met Office (the UK’s main source of information about weather) averages from 1971-2000. All the statistics are only rough ideas as conditions can vary hugely even within England.
