🇺🇸 New Orleans vs 🇺🇸 San Francisco

New Orleans below sea level in the Mississippi Delta has one of America's most extreme weather environments. The city is surrounded by water — the Mississippi River, Lake Pontchartrain, and the Gulf of Mexico — creating persistent intense humidity. Hurricane Katrina in 2005 catastrophically flooded 80% of the city, reshaping the climate risk consciousness of everyone here.

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.
