🇺🇸 San Francisco vs 🇺🇸 Vail

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.

Vail at 8,150 feet in the Gore Creek valley is one of the world's premier ski destinations. The valley orientation traps Pacific moisture from the west, delivering reliable heavy snowfall. Cold valley inversions are intense in winter while summer afternoons bring predictable thunderstorms over the surrounding peaks.
