Ghana has three hydro-climatic zones. The South-Western system is the most humid part of the country, with mean annual rainfall between 1500 mm and 2000 mm. The Volta basin system, covering the northern part of the country, has mean annual rainfall of about 1000 mm in the savanna area and about 1500 mm to 2000 mm in the forest area. The Coastal basin system is the driest, with mean annual rainfall of about 900 mm. Ghana’s climate is tropical and strongly influenced by the West African monsoon. Seasonal variations in temperature in Ghana are greatest in the north, with highest temperatures in the hot, dry season (April, May, and June) at 27‐30°C; further south, temperatures are lower (June, August, September) at 22‐25°C.
