Seattle in August
Great time to visit
August extends July's perfect weather but adds more heat and humidity. Still prime Seattle season, though some locals escape to the mountains to avoid tourist crowds.
Weather
August continues the dry, sunny pattern with the warmest temperatures of the year. Occasional heat waves push thermometers into the 80s and 90s Fahrenheit. Marine layer provides natural air conditioning most mornings.

All Months
June through September delivers Seattle at its absolute best. Temperatures hover in the 70s, rain takes a vacation, and the city comes alive with outdoor festivals and markets. July and August see the least rain but also the highest hotel prices and biggest crowds at popular spots like Pike Place Market. September might be the sweet spot — still warm, fewer tourists, and the leaves start changing in nearby mountains. Spring arrives late but brings blooming cherry trees around the University of Washington quad in March and April. Winter gets dark and wet, but it's also when you'll find the best hotel deals and shorter lines at restaurants. The holiday season brings charm with Christmas markets and lights, just pack waterproof everything. Avoid visiting during tech conference season in late spring unless you enjoy inflated hotel rates and crowded coffee shops full of startup bros.
