🇮🇹 Milan vs 🇺🇸 New York City

Milan sits in the western Po Valley, one of Europe's most fog-prone and humidity-trapping basins, hemmed in by the Alps to the north and the Apennines to the south. The city experiences hot, humid summers with weak ventilation and cold, damp winters where temperature inversions trap pollution and moisture at ground level. The Navigli canal system and proximity to several pre-Alpine lakes introduce subtle moisture gradients, while the dense urban core generates one of Italy's strongest urban heat island effects.

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.
