🇺🇸 Rochester vs 🇺🇸 San Francisco

Rochester on Lake Ontario is New York's third-largest city and equally famous for lake-effect snow but from Lake Ontario rather than Erie. The city averages 100 inches of snow annually. Rochester also claims the least sunny days in the US — the cloud cover from Lake Ontario is persistent from October through May.

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.
