🇮🇹 Milan vs 🇮🇳 Mumbai

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.

Tropical monsoon — hot and humid year-round, extreme monsoon season

Mumbai has one of the world's most dramatic monsoon seasons. The southwest monsoon (June–September) dumps enormous rainfall, regularly flooding the city. The dry season (November–February) is the time to visit with warm but manageable conditions.
