🇬🇭 Accra vs 🇮🇳 Kolkata

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.

Kolkata's tropical wet-and-dry climate is dominated by the Bay of Bengal monsoon, the Hooghly River corridor, and the vast deltaic floodplain of the Ganges. The city experiences extreme humidity from May through October, with the river and surrounding wetlands amplifying moisture levels, while winter months bring dry northwesterly winds and brief cool spells. The dense urban core generates a pronounced heat island effect, but the Hooghly riverfront, the East Kolkata Wetlands, and the Maidan parkland create significant cooling corridors that shape neighborhood-level weather.
