🇺🇸 Indianapolis vs 🇺🇸 San Francisco

Indianapolis in central Indiana has a variable humid continental climate with no major terrain features to modify weather. The city sits at the crossroads of multiple air mass pathways, meaning rapid weather changes are common. The Indianapolis 500 in late May historically captures the transition between late spring severe weather and summer heat.

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.
