🇮🇳 Kolkata vs 🇳🇬 Lagos

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.

Tropical monsoon — hot and humid year-round with distinct wet and dry seasons

Lagos is hot and humid year-round. The wet season (April–October) brings heavy rains and periodic flooding; the dry season (November–March) is the best time to visit. The harmattan wind (December–February) brings dry, hazy air from the Sahara.
