🇺🇸 Baltimore vs 🇺🇸 San Francisco

Baltimore on the Chesapeake Bay has a humid subtropical climate modified by the Bay's thermal mass. The Chesapeake moderates temperatures year-round, but summer humidity is intense and the city has significant heat vulnerability in its dense rowhouse neighborhoods. Hurricane remnants and nor'easters both affect the city seasonally.

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.
