🇮🇹 Milan vs 🇮🇹 Rome

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.

Mediterranean — hot dry summers, mild wet winters, abundant sunshine

Rome's climate is quintessentially Mediterranean. Summers are hot and dry with intense sun. Winters are mild and occasionally rainy. Spring and fall are extraordinary for sightseeing.
