What's a good time of year to visit Seattle?

Response:
The best time of year to visit Seattle is in the summer. The weather is nicest from June to September, and there are many outdoor activities to enjoy. However, there is lots to do all year. For example, in spring many visitors come to the University of Washington campus to see cherry blossoms. The nearby tulip festival in the Skagit Valley is another popular spring attraction.
