There is a common misconception that all of Scotland suffers from very high rainfall. This is simply not true, and much of the east coast actually receives less rainfall than southern counties of England.

Indeed, some northern and southern parts of Scotland regularly receive less than 250mm of rain during the four summer months. It has also to be acknowledged that the rainfall is higher on the west coast, where it follows a well defined seasonal pattern dictated by the passage of Atlantic depressions which are most frequent in the autumn and winter months.

During spring and early summer the weather is usually controlled by the southward migration of the jet stream and the Arctic high pressure system, often resulting in dry and settled weather.
