🇺🇸 Brockton vs 🇺🇸 San Francisco

Brockton in southeastern Massachusetts south of Boston has a coastal New England climate with Atlantic influence. Its position on the Atlantic coastal plain gives it slightly milder winters than Boston with less snowfall but the city is still fully in the nor'easter track. Dense urban development creates heat island effects.

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.
