🇬🇭 Accra vs 🇮🇳 Chennai

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.

Chennai's tropical wet-and-dry climate is defined by its long Bay of Bengal coastline, which delivers the northeast monsoon from October to December — the city's primary rainy season, unusual for an Indian metro. The flat coastal plain offers little topographic relief, so microclimates are driven primarily by proximity to the sea, river corridors along the Adyar and Cooum, and dramatic variation in building density and green cover. Summer temperatures routinely exceed 40°C inland while coastal neighborhoods benefit from steady onshore sea breezes that moderate heat by 3–5°C.
