From festivals and live performances to fairs, parks, gardens and family activities, there is always something new to discover.
I’ve put together some of the best things to do in Seattle and around the Puget Sound this month. Think of this as less of a tourist checklist and more of a local guide to finding events, seasonal favorites and fun reasons to get out and explore.

Seattle’s September calendar is packed with festivals, performances, fairs and outdoor events. If you’re wondering where to start, here are a few of this month’s highlights:
Join Us!
September in Seattle is where summer and fall meet. The days are still pleasantly warm, but there’s a crispness beginning to creep into the mornings and evenings. Summer crowds start to thin, the first hints of fall color appear, and the city settles into a slightly slower rhythm while there’s still plenty of sunshine left to enjoy.
Mornings are perfect for grabbing coffee and heading to a farmers market, walking along the waterfront, or squeezing in a hike before the weather begins to change. Afternoons can still feel like summer, with plenty of opportunities for boating, exploring a neighborhood, or catching a Mariners game. As evening arrives a little earlier, patios are still lively, but cozy restaurants and neighborhood gathering spots start becoming more inviting again.
September is one of Seattle’s underrated months. You get a little bit of everything: lingering summer weather, the beginning of fall, fewer crowds, and plenty happening around the city. It’s the perfect time to enjoy those last warm days while welcoming the changing season and everything that makes early fall in the Pacific Northwest so special.
