🇺🇸 Cedar Rapids vs 🇺🇸 San Francisco

Cedar Rapids on the Cedar River was devastated by a 500-year flood in 2008 and by the derecho of 2020 that knocked down millions of trees. The city has a humid continental climate with the open Iowa prairie providing no barriers to weather extremes. The Cedar River valley creates humidity and flood risk.

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.
