The Northern Region is located in North Ghana. It is the largest of ten regions coverings an area of 70,384 square kilometers or 31 percent of Ghana's area . Northern Region is divided into 20 districts. The Northern Region's capital is Tamale.
The Northern Region is much drier than southern areas of Ghana, due to its proximity to the Sahel, and the Sahara. The vegetation consists predominantly of grassland, especially savanna with clusters of drought-resistant trees such as baobabs or acacias. Between May and October is the wet season, with an average annual rainfall of 750 to 1050 mm (30 to 40 inches). The dry season is between about November and April. The highest temperatures are reached at the end of the dry season, the lowest in December and January. However, the hot Harmattan wind from the Sahara blows frequently between December and the beginning of February. The temperatures can vary between 14 °C (59 °F) at night and 40 °C (104 °F) during the day.
The political administration of the region is through the local government system. Under this administration system, the region is divided into 20 districts. Each District, Municipal or Metropolitan Area, is administered by a Chief Executive, representing the central government but deriving authority from an Assembly headed by a presiding member elected from among the members themselves.
