Average annual rainfall and mean annual water deficit data of some 46 stations in the forest zone are presented. Lines joining up points with 400 mm and 250 rom mean annual water deficits are drawn on a map to indicate those areas climatically suitable and favourable, respectively, for oil palm cultivation. Three of the four existing oil palm plantations in Ghana are shown to be situated in marginal areas and the fourth and largest one (Pretsea, 3100 ha) is also outside the climatically favourable area. Tentative estimates of bunch yield are 12-15 t/ha (5-6 t/acre) at maturity when the average annual water deficit is below 250 mm.
