Tacoma Weather in September

Tacoma on Puget Sound south of Seattle has a classic Pacific Northwest marine climate with Tacoma-specific influences from the Puyallup River delta and the Mount Rainier viewshed. The Sound moderates temperatures and the 'Tacoma Aroma' from the pulp mill is more weather-related than many realize — humidity affects how strongly organic compounds disperse.

Excellent shoulder season — warm with fewer tourists in many destinations.
