🇺🇸 Lowell vs 🇺🇸 San Francisco

Lowell at the confluence of the Merrimack and Concord Rivers is the birthplace of the American Industrial Revolution. The river valleys create local weather patterns with valley fog, channeled winds, and humidity from the rivers. Located north of Boston, it sees slightly more extreme winter temperatures with additional snowfall.

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.
