🇺🇸 San Francisco vs 🇺🇸 Tacoma

San Francisco's climate is shaped by its position on a peninsula surrounded by the Pacific Ocean and San Francisco Bay. The coastal fog (Karl the Fog) rolls in through the Golden Gate each summer afternoon, keeping temperatures mild year-round. The city has dramatically different microclimates — the Sunset District fog-bound while the Mission basks in sun on the same day.

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.
