Ziguinchor is the capital of the Ziguinchor Region, and the chief town of the Casamance area of Senegal, lying at the mouth of the Casamance River. It has a population of over 230,000. It is the seventh largest city of Senegal, but largely separated from the north of the country by The Gambia.
Unlike the semi-arid to arid north of Senegal, as it is under the influence of the West African Monsoon, Ziguinchor has a tropical savanna climate, with an average annual accumulated rainfall of approximately 1,547 millimetres or 61 inches.
