🇺🇸 Cambridge vs 🇺🇸 San Francisco

Cambridge across the Charles River from Boston is home to Harvard and MIT. The city's climate is closely tied to Boston's — marine influence from the harbor moderates extremes while nor'easters bring heavy snow. The Charles River provides a weather corridor and urban heat island effects are present but moderated by Cambridge's significant green spaces.

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.
