🇺🇸 San Francisco vs 🇺🇸 Trenton

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.

Trenton, New Jersey's capital, on the Delaware River has a humid subtropical climate at the transition with humid continental. The Delaware River provides humidity and flooding risk while the city's industrial legacy has created heat island effects that exceed neighboring communities. Washington crossed the Delaware near here — winter weather at the river can be dramatic.
