🇺🇸 Ann Arbor vs 🇺🇸 San Francisco

Ann Arbor is home to the University of Michigan and has a full humid continental climate west of Detroit. Less lake-influenced than Grand Rapids, the city sees more extreme temperature swings. The Huron River provides some cooling through the city while Michigan Stadium (largest in the US) creates its own weather microclimate during games.

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.
