The region has a tropical climate, with high temperatures averaging 23.9oC (750F) and a double
maxima rainfall pattern. Rainfall ranges, from an average of 1000mm millimetres in the northern
parts to 1400 millimetres in the southern parts.
Vegetation
The region has two main vegetation types, the moist semi-deciduous forest, mostly in the southern
and southeastern parts, and the guinea savannah woodland, which is predominant in the northern
and northeastern parts of the region. The level of development and variations in economic activity
are largely due to these two vegetation types. For example, the moist semi-deciduous forest zone is
conducive for the production of cash crops, such as cocoa and cashew. Brong Ahafo is one of the
three largest cocoa producing areas in the country, mainly in the Ahafo area, which shares common
border with western Ashanti. A lot of the cashew in Ghana is produced in Brong Ahafo, some of which
are processed into brandy and cashew wine at Nsawkaw in Wenchi. Timber is also an important
forest product, produced mainly in the Ahafo area around Mim, Goaso and Acherensua. Other cash
crops grown in the forest area are coffee, rubber and tobacco. The main food crops are maize,
cassava, plantain, yam, cocoyam, rice and tomatoes. Yam production is very high in the guinea
savannah zone, around Techiman, Kintampo, Nkoranza, Yeji, Prang and Kwame Danso.
