🇺🇸 New York City vs 🇺🇸 Philadelphia

Humid continental — hot summers, cold winters, year-round precipitation

New York City has four distinct seasons. Fall is the sweet spot: mild temps, low humidity, and the city at peak energy. Summers are hot and muggy; winters bring snow and bitter wind chill, especially near the waterfront.

Philadelphia in the Delaware River valley has a humid subtropical climate transitioning to continental. The city's urban heat island is intense — dense rowhouse neighborhoods without significant green space are among the East Coast's most heat-vulnerable. The Delaware and Schuylkill Rivers provide some humidity while the Piedmont hills to the north create varied terrain.
