'Varied' describes Scotland's climate perfectly. There are wide variations in climate over small distances, and a sunny day will often as not be followed by a rainy one. Although the country nudges the Arctic Circle, the Gulf Stream winds keep the temperature mild (well, relatively mild). The Highlands, however, can have extreme weather at any time. The east coast tends to be cool and dry, with winter temperatures rarely dropping below freezing (but watch out for the bone-chilling winds off the North Sea). The west coast is milder and wetter, with average summer highs of 19°C (66°F). May and June are the driest months; July and August the warmest. In the north the summer sun barely sets; the winter sun barely rises.
