The weather in Scotland does not differ that much from England although Scotland is a bit more cloudy. The most of the sunshine is for Ayrshire, Lothians, Angus and Fife, the least for the mountains in the Highland region. The average sunshine hours are at their maximum in May and June and the least in December and January. Because of the high latitude the winterdays are very short but are compensated with long summerdays with only 5 hours of “almost darkness”.
Rainfall is another key element of Scottish weather although it is not as bad as sometimes told. Some areas receive about 3,000 mm per year (the western Highlands) and other areas only 800 mm per year (the east coast). Measurable rainfall occurs on over 250 days in the Highlands to 175 days per year in other parts.                                                                                                    Annual sunshine chart
