The following factors affect cocoa and coffee production:
Coastal regions have earlier rains than Mamfé and in these area the cocoa is harvested earlier; the latest harvests are in the NW of the MACEFCOOP area.
Affecting roads:
The journey between Mamfé and Douala takes 6 hours in good conditions, but can easily take 2 days in the wet season.

Mamfé monthly rainfall average (inches)
Blackpod is a particular problem during the September rains

Towns such as Eyumojock are typically clearings of less than 10 acres surrounded by tall, dense, near-primordial rain forest.
The rain forest is thick enough to limit travel to well-used footpaths and roads that become nearly impassable in the wet season....(?)
There are three seasons in the southern part of Cameroon: a sustained dry season from November to February, light rains from March to June, and heavy rain from August to October. The average temperature is about 26° but altitude has a significant effect, accounting for significant variety of vegetation.
The MACEFCOOP area is hilly averaging 500-800 meters above sea level, draining from the old volcanic hills to the east. The main rivers of the area are tributaries of the Cross River.

of Manyu and Lebialem Divisions of the Cameroon's South-west Province in which
MACEFCOOP members farm for coffee and cocoa. Also shown are the 200m, 500m,
1000m and 2000m contours, illustrating how the MACEFCOOP area slopes and drains
from the volcanic hills of the east, to the lower areas adjacent to the border
with Nigeria. The Nguti subdivision is immediately south of the MACEFCOOP
area.
