Current Climate


This page presents Gabon'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.


Gabon is largely composed of plateaus and hills, covering 3/4 of the area of the country, with the highest mountain reaching 1000 m. Gabon has an extremely dense hydrological network that feeds two rivers: Ogooué and Nyanga, as well as high basins of small northern coastal rivers. The country has a moist, hot climate of typically tropical regions. Precipitation is abundant and spread almost throughout the year, typically ranging from 1500 mm to 3500 mm per year. The country has a single wet season between October and May, with a mean monthly rainfall of 200‐250 mm. Temperatures are high and remain relatively constant throughout the year, averaging 25-27°C in coastal lowlands and 22‐25°C inland. January to April is typically the hottest season.
