🇬🇭 Accra vs 🇮🇹 Milan

Tropical savanna — hot year-round, two rainy seasons, harmattan dry season

Accra sits on the Gulf of Guinea near the equator. It's hot year-round but less humid than Lagos due to the cold Benguela current offshore. The Harmattan (November–March) brings dry, hazy conditions from the Sahara. Two rainy seasons: March–July and September–October.

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.
