- Climate
The coastal areas and most of the inland regions of Guinea have a tropical climate, with a rainy season lasting from May to October, uniformly warm temperatures, and moderate to high humidity. The upper Guinea region has a hotter, drier, more desert-like climate. The Niger, Gambia, and Senegal Rivers are among the 22 West African rivers that originate in Guinea. Conakry is located on a narrow, 36-kilometer-long peninsula that juts into the Atlantic Ocean. The peninsula has low, rolling hills, tropical vegetation, and many vistas of the sea. Conakry’s year-round high temperature averages 85°F, and rarely rises above 90°F or falls below the mid-70s. Relative humidity is generally 70% or higher. Conakry’s average annual rainfall of 169 inches, almost all of which falls during the May-October period, makes it one of the world's rainiest capital cities. Americans living in Guinea generally find the climate pleasant overall, although the dry season can be very dusty and the rainy season quite damp.
