🇺🇸 San Francisco vs 🇺🇸 Scottsdale

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.

Scottsdale shares Phoenix's desert heat but its eastern position against the McDowell Mountains provides some terrain variation. The city blends dense resort corridors with luxury desert communities that leverage elevation for cooling. Summer temperatures regularly exceed 110°F in the valley floor areas.
