Ben Nevis, the highest peak in the British Isles.

The climate of Scotland is temperate, and tends to be very changeable. It is warmed by the Gulf Stream from the Atlantic, and as such is much warmer than areas on similar latitudes, for example Oslo, Norway. However, temperatures are generally lower than in the rest of the UK, with the coldest ever UK temperature of -27.2°C (-16.96°F) recorded at Braemar in the Grampian Mountains, on January 10, 1982 and also at Altnaharra, Highland, on December 30, 1995. Winter maximums average 6°C (42.8°F) in the lowlands, with summer maximums averaging 18°C (64.4°F). The highest temperature recorded was 32.9°C (91.22°F) at Greycrook, Scottish Borders on August 9, 2003. In general, the west of Scotland is usually warmer than the east, due to the influence of the Atlantic currents, and the colder surface temperatures of the North Sea. Tiree, in the Western Isles, had 300 days of sunshine in 1975. Rainfall varies widely across Scotland. The western highlands of Scotland are the wettest place, with annual rainfall exceeding 120 inches (3,000 mm). In comparison, much of Scotland receives less than 31 inches (800 mm) annually, and eastern and southern parts of the country receive no more rainfall than the driest parts of England. Snowfall is not common in the lowlands, but becomes more common with altitude. Braemar experiences an average of 59 snow days per year, while coastal areas have an average of less than 10 days.
