🇺🇸 Hartford vs 🇺🇸 San Francisco

Hartford in the Connecticut River Valley has a humid continental climate, sheltered from direct ocean influence by the hills to the southeast. This valley position gives Hartford hotter summers and colder winters than coastal Connecticut. The river moderates temperatures somewhat while creating fog and humidity along its banks.

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.
