The Sissala West district is located in Guinea Savanna vegetation belt. This vegetation consists of grass with scattered drought resistant trees such as the shea, the baobab, dawadawa, and neem trees. The heterogeneous collection of trees provides all domestic requirements for fuel wood and charcoal, construction of houses,cattle kraals and fencing of gardens (especially dry season farming). Again, the shorter shrubs and grass provide fodder for livestock.
The climate of the district is one that is common to the three northern regions. There are two main seasons, the dry and the wet season. The wet season commences in April and end in October. The dry season, characterized by the cold and hazy harmatan weather, starts from early November and ends in the latter part of March when the hot weather begins.
The long dry season requires the establishment of irrigation facilities. The mean annual rainfall is about 1100mm with its peak in August. Relative humidity is between 70% and 90% in the rainy season but is as low as 20% in the dry season.
