Warm summers, mild winters, heavy rain. Most rain falls over the mountains in the west, especially Snowdonia in Wales and the Scottish Highlands.
The reason for Britain's weather being different North, South, East and West is because different air masses (wind) come from each direction as follows: North - Arctic very cold
East - Continental from Europe and Asia. The winds are cold and dry.
South - Tropical warm.
West - Maritime air has crossed Atlantic bringing cloud and rain. The winds are warm and wet.
