Best Time to Visit Seattle

The best time to visit Seattle weather-wise is during the summer months, from June to August, when the temperatures range from 70°F to 80°F (21°C to 27°C). This is the ideal time to enjoy outdoor activities such as hiking, sightseeing, and visiting the city's parks and waterfront. However, summer is also peak tourist season, which means higher prices, crowded attractions, and occasional traffic congestion.

Spring (March to May) and fall (September to November) offer milder temperatures and fewer crowds compared to summer. Spring brings blooming cherry blossoms and the famous Skagit Valley Tulip Festival, while fall offers beautiful foliage and cultural events like the Seattle International Film Festival. However, both seasons also experience more rainfall compared to summer, and there is a possibility of encountering some cloudy days. Winter (December to February) is the coldest and wettest season in Seattle, with temperatures averaging around 40°F (4°C) and frequent rain. While hotel rates are at their lowest and attractions are less crowded, outdoor activities may be limited due to the weather, and there is a chance of encountering storms. However, winter in Seattle also brings festive events like the Seattle Christmas Ship Festival and the Winter Solstice Night Market.
