🇺🇸 Rockford vs 🇺🇸 San Francisco

Rockford on the Rock River in northwestern Illinois has a full humid continental climate. Positioned between Lake Michigan and the Mississippi River, it sees heavy lake-effect snow when winds blow from the northeast. Winters are harsh and summers warm and humid with frequent severe thunderstorms.

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.
