🇨🇮Ivory Coast

Côte d'Ivoire stretches from 4°18′ to 10°44′N along West Africa with a 515 km Atlantic coast, mostly low rolling savanna and forest plain (250–400 m) rising to the Nimba massif on the Liberian–Guinean border (Mt Nimba 1,752 m, the country's highest peak); the climate transitions north–south from tropical monsoon (Am) along the southern coast (Abidjan, San-Pédro), through tropical savanna (Aw) in the central forest–savanna mosaic (Yamoussoukro, Bouaké), to Sudano-Sahelian (BSh) in the far north (Korhogo, Ferkessédougou).

Abidjan averages 27°C year-round with 1,800 mm rain split between a long wet season May–July and a short Oct–Nov peak; the southwestern coast (Tabou) is one of the wettest spots in West Africa with over 2,200 mm; the central forest–savanna transition (Bouaké) sees ~1,150 mm in a single rainy peak Apr–Oct; the dry north receives 1,000 mm with a sharp Nov–Mar dry season dominated by the harmattan dust haze. The West African monsoon and ITCZ migration drive the rainfall regime; coastal erosion is severe along Grand-Bassam–Port-Bouët; ENSO and Atlantic dipole modulate rainfall variability.
