🇺🇸 San Francisco vs 🇺🇸 Vancouver

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.

Vancouver Washington (not Canada) sits across the Columbia River from Portland, sharing its Willamette Valley climate but with some differences from the river position. The Columbia creates a weather boundary and occasional east winds from the Gorge can be extreme. Vancouver benefits from Oregon's outdoor-focused culture while avoiding Oregon's income tax.
