🇺🇸 Aspen vs 🇺🇸 San Francisco

Aspen at 7,908 feet in the Roaring Fork Valley is one of America's most dramatic mountain climates. The valley's deep orientation creates powerful temperature inversions with cold air pooling on the valley floor. Heavy snowfall averages 200+ inches annually, and afternoon thunderstorms in summer are intense over the surrounding fourteeners.

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.
