Washington Weather

Washington Home | Washington Sitemap
Washington has two main climate zones. The western part of the state has a mild, humid climate. A cool, dry climate is found east of the Cascade Mountain Range. On the Pacific coast the average annual temperature ranges from 51 degrees F to 40 degrees F. A wet marine climate dominates western Washington, where frequently overcast skies, dense fog, and consistent, heavy rainfall are common. Summers are sunnier. East of the Cascade Range, however, annual precipitation only amounts to around 6 inches, though precipitation does increase closer to the Rocky Mountains.
