United Kingdom weather overview

No wonder the British are obsessed with the weather: they have one of the world's most changeable climates. The general pattern is for summers to be warm and wet and winters to be cool and wet. However, the quirky weather can leave the islands basking in sunshine as hot as the Mediterranean's during a good summer and shivering in temperatures as cold as Moscow's during a particularly harsh winter.

In the United Kingdom, weather conditions vary widely from day to day and from region to region. The southwest is the warmest area while the west coast and the mountains attract the most rain. The east coast is generally a chilly and blustery region with colder winters than other areas. London and the southeast enjoy more periods of sunshine and are drier and warmer than the north.

The mountains of Scotland, Wales and northern England can be treacherous. In the summer months, they can record some of the highest rainfall in Europe while, in winter, they are prone to blizzards, gales and icy rain. Unwary mountain walkers frequently have to be rescued when a sudden turn in the weather leaves them stranded and in danger of frostbite or worse.

Scotland, because of its northerly latitude, experiences longer days in the summer and shorter days in the winter than anywhere else in the UK but, as a rule, temperatures there are no lower than in England. The west of the country is warmer and rainier than the east and visitors exploring the Highlands should be prepared for sudden fog and mists.

Wales is generally less sunny and more rainy than England but its coasts can enjoy prolonged periods of sunshine in the summer and are therefore popular with tourists. The Welsh Mountains should be approached with respect at any time of year as conditions can quickly turn nasty. Northern Ireland suffers highly changeable weather conditions and tends to be wetter with less sun than other parts of the UK.

What to pack for United Kingdom weather

Always bring a range of clothing when touring Britain. Layered clothing, which can be added to or removed according to temperature and conditions, is probably the best bet. Expect the odd short sharp shower and, if in the Lake District or the mountains, rainwear is strongly recommended.
