🇺🇸 San Francisco vs 🇺🇸 Wilmington

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.

Wilmington at the confluence of the Christina and Brandywine rivers near Delaware Bay has a humid subtropical climate. The Delmarva Peninsula's coastal position moderates temperatures with Delaware Bay proximity providing coastal influence. The city gets precipitation from both Atlantic nor'easters and Gulf moisture systems moving north.
