However, the best time to visit Seattle is between July and mid-October when the average temperature ranges between 15? to 23?. During these months, the skies are clear with minimal rain, and one can opt for several outdoor activities. It also implies that these months are the high season of Seattle. The time between mid-October to February is best for visiting museums, restaurants, and Pike Place Market.
