Climatology
This page presents Cameroon's climate context for the current climatology, 1991-2020, derived from observed, historical data. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. You can visualize data for the current climatology through spatial variation, the seasonal cycle, or as a time series. Analysis is available for both annual and seasonal data. Data presentation defaults to national-scale aggregation, however sub-national data aggregations can be accessed by clicking within a country, on a sub-national unit. Other historical climatologies can be selected from the Time Period dropdown list.
Observed, historical data is produced by the Climatic Research Unit (CRU) of University of East Anglia. Data is presented at a 0.5º x 0.5º (50km x 50km) resolution.
Cameroon has one main rainy reason that lasts from May-November when the West African Monsoon brings moist air over the country from the Atlantic Ocean. The peak rainy months correspond with the lowest average temperatures of the year. The Southern Plateaus experience two shorter rainy seasons during May-June and October-November. Cameroon’s dry season lasts from December-April and corresponds with the highest average temperatures of the year during the latter part of the season in the months of February-April. The southern part of the country is characterized as humid and equatorial with temperatures ranging from 20-25°C (depending on altitude) and the wettest regions receiving more than 400 mm of rainfall per month. Northern Cameroon (north of 6°) is semi-arid and dry with temperatures ranging from 25-30°C. This portion of the country receives less than 100 mm of rainfall per month.
