🇺🇸 Duluth vs 🇺🇸 San Francisco

Duluth on the western tip of Lake Superior has the most dramatic lake-effect climate in the country. Lake Superior — the world's largest freshwater lake — keeps the city remarkably cool in summer (rarely above 80°F) while lake-effect snowstorms can be intense. The city's dramatic hillside topography creates strong elevation weather differences.

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.
