Washington has two main climates: west and east of the Cascades. The west is typically mild and wet, the east cool and dry. Seattle temperatures generally range from the very low single digits in January to about 20 degrees (Celsius) in July; Spokane from about minus six in January to about 20 in July.Most rain falls October through March. The western side of the Olympic Peninsula receives up to 406cm (160 inches) of rain annually, and the western slopes of the Cascades over 500cm (200 inches) of snow. Eastern Washington has only about 15cm (six inches) of precipitation, with more closer to the Rocky Mountains.
With several regional airports, flying within Washington is easy and discount fares are available. There is train service north and south of Seattle and bus service to Spokane and beyond. Washington has the most extensive ferry service in the country, and it includes transport to the San Juan Islands, Bainbridge Island, Whidbey Island, Vashon Island, and Kitsap Peninsula. A car or RV is a great way to see the state and the only way to get to some of the more remote locations. Make sure to fill the gas tank first — Washington is a large state, and gas stations are few and far between in some areas.
Seattle is fun to explore on foot and is well served by the Metro system. The Downtown Ride Free Area has free bus service from 6am to 7pm. To travel across the sound, choose from ferries, speedboats, water taxis, and jet catamarans. Seattle is a difficult city for driving, with bad traffic congestion, one-way streets, and scarce and expensive parking.
Hiking is the best mode of transport in Olympic National Park. A great state for hiking, Washington’s popular trails include the Pacific Crest Trail, Hoh River Trail, and Wonderland Trail.
