Washington’s climate varies greatly from west to east. A Mediterranean climate predominates in western Washington, and a much drier semi-arid climate prevails east of the Cascade Range. In the autumn and winter Washington’s prevailing winds come from the southwest, and bring relatively warm and moist air masses and a predictably wet season.

Western Washington is known for its mild climate, considerable fog, frequent cloud cover, long-lasting drizzles in the winter and warm, temperate summers. The Eastern region, which does not benefit from the general moderating effect of the Pacific Ocean, occasionally experiences extreme climate.
