🇺🇸 Dallas vs 🇺🇸 San Francisco

Dallas in north Texas has an extreme continental climate with scorching summers and cold winter blue northers. The 2021 winter storm Uri brought unprecedented cold to Dallas with temperatures below 0°F, killing hundreds and causing catastrophic infrastructure failure. Summers regularly exceed 100°F for weeks. The city sits on the prairie with no terrain features to moderate extremes.

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.
