When to fly to Washington StatePeak Season:
It rains a lot in Seattle but there is much less rain from April to October, and because the summer weather is mild, any time during this half of the year is pleasant. Summer is the most popular time and when most people visit Seattle. It stays light until 10pm in June and July. Summer is when the big, primarily outdoor festivals are held. During the occasional summer rain, there is nearly always something to see in the theatres and performance halls. Higher rates tend to be from around mid-May to mid-September.
The rainy season goes from October to April. The most pleasant weather in more-or-less off-season times occurs in early May and late September, making this a great time to find cheap plane tickets.
Getting around Washington State
The Metro Transit system of buses, including electric and hybrid buses, is useful and tourist-friendly, though drivers do not carry change. Express routes are offered by some buses. Other options include the streetcar and the monorail, connecting with major attractions. The Washington State Ferries are a tourist attraction in their own right.
Seattle is generally safe, though common sense should be applied at all times and it can be best to avoid parks at night.
