The average annual temperature ranges from near 51 degrees along the Pacific Ocean coastline, to near 40 degrees in the far northeast.
Western Washington is mild because of the warm currents coming off the North Pacific Ocean. This area has frequent cloud cover, considerable fog and long-lasting drizzles. Summers are much sunnier, yet still mild, with an average high near 70 degrees.
Along the western edges of the Olympic Peninsula, up to 160 inches of annual rain is the norm, making it the wettest area of the 48 continental states. Weeks or even months may pass without a clear, sunny day.
The western slopes of the Cascade Range receive some of the heaviest annual snowfall in the country (over 200 inches annually).
