Best Time To Visit Seattle
A month-by-month guide to weather, crowds, and travel conditions in Seattle, USA.
About Seattle
Seattle sits between Puget Sound and two volcanoes: Pike Place's market theater, the Space Needle and Chihuly glass, ferries across the Sound, coffee culture at industrial scale, and — July through September — the sunniest, driest summer days of any major American city. The mountains (Rainier, Olympics) run the horizon.
