🇺🇸 Sacramento vs 🇺🇸 San Francisco

Sacramento has a hot-summer Mediterranean climate with the hottest summers of any major California city, frequently exceeding 100°F. The Delta Breeze — cool marine air pushed through the Golden Gate and delta by inland heating — brings reliable evening cooling and makes hot days more bearable. Winters are mild but the valley fills with thick tule fog for weeks at a time.

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.
