As in most of West Africa, Nigeria's climate is characterized by strong latitudinal zones, becoming progressively drier as one moves north from the coast. Rainfall is the key climatic variable, and there is a marked alternation of wet and dry seasons in most areas.
About two-thirds of Nigeria lies in the watershed of the Niger River, which empties in to the Atlantic at the Niger Delta, and its major tributaries: the Benue in the northeast, the Kaduna in the west, the Sokoto in the northwest, and the Anambra in the southeast.
Nigeria has many local festivals that date back to the time before the arrival of the major religions, and which are still occasions for masquerade and dance. The local festivals cover an enormous range of events, fromMada Dancers harvest festivals and betrothal festivals, to the investing of a new chief and funerals.
