🇺🇸 Birmingham vs 🇺🇸 San Francisco

Birmingham has a humid subtropical climate with hot, humid summers and mild winters. The city sits in the Jones Valley between Red Mountain and Shades Mountain, which creates local temperature inversions and traps humidity. Thunderstorm activity is frequent in spring and summer.

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.
