The climate of Washington (United States of America)
The state of Washington is located in the northwestern part of the United States and is not to be confused with the capital, Washington D.C. Washington was named after the first president of the United States, George Washington. Washington is located on the Pacific Ocean and has a varied landscape. The landscape of Washington consists of low, flat plains, rugged mountainous regions, an active volcano (Mount Saint Helens), forests and hills. Several mountainous regions in Washington influence the climate and weather of the state. The most dominant mountain range is the Cascade Mountain Range, also known as Cascade Range. Washington has several climate types which are quite unique in the United States. The largest part of Washington has a moderate Mediterranean climate (type Csb) with fairly dry summers, wetter winters and moderate temperatures all year round. The northwestern part of the state of Washington has a moderate maritime climate which changes into a warm maritime climate. In general, the Pacific Ocean has a warming effect during the winter making extremely low temperatures uncommon. During the summer heat is tempered by the Atlantic Ocean. Washington is among the wettest states in the United States. Precipitation figures are highest in the Cascade Mountain Range.
