🇺🇸 San Francisco vs 🇺🇸 Waterbury

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.

Waterbury is Connecticut's most inland major city, sitting in a steep-sided valley of the Naugatuck River. This valley position creates cold air pooling in winter, making temperatures colder than the Sound coast. The valley also traps summer heat and humidity, making Waterbury one of the hotter spots in Connecticut during heat waves.
