Spring
Spring in Seattle tends to bring milder temperatures and fewer crowds than the peak summer months, making it a solid pick for travelers who want to see the main sights without fighting through lines. Gardens and outdoor spaces are usually at their best this time of year.
Summer
Summer is generally the busiest stretch of the year in Seattle, with long daylight hours and the widest range of tours and outdoor activities running on full schedules. Expect bigger crowds and higher prices at the most popular attractions.
Autumn
Autumn tends to be a quieter, more comfortable time to visit Seattle, with crowds thinning out after the summer rush and temperatures generally easing into a more pleasant range for walking tours and sightseeing.
Winter
Winter is typically the slowest season in Seattle, which can mean better rates on tours and accommodations, though some outdoor attractions may run on reduced hours. It’s a reasonable trade-off for travelers who prioritize lower costs and thinner crowds over ideal weather.
