Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. Explore the overview for a general context of how climate change is affecting Benin.

Climate Data Projections

The climate science community sources a suite of global climate models to help decision makers understand the projections of future climate change and related impacts, among the most widely used are the Coupled Model Intercomparison Project, Phase 5 (CMIP5) models included in the IPCC's Fifth Assessment Report (AR5). Climate projections can be presented via individual models or through multi-model ensembles. The Climate Change Knowledge Portal (CCKP) supports the analysis of climate impacts using multi-model ensembles, as they represent the range and distribution of the most plausible projected outcomes when representing expected changes.


  • Mean annual temperatures are projected to rise by 1.0-3.0° C by the 2060's, with the northern regions of Benin experiencing the most rapid increase.
  • Mean annual temperatures over West Africa are projected to increase by 3°C to 6°C by the end of the 21st century for under RCP4.5 and RCP8.5.


  • Rainfall projections in Benin have better consistency on the seasonal level than the annual level. Projections tend towards decreases in rainfall during January-March and April-June, and increases during July-September and October-December.
  • By the end of the 21st century many CMIP5 models project mean precipitation over West Africa to increase during the rainy season with a small delay to the start of the rainy season. 

This section provides the options to visualize climate variables and indices derived from scientifically vetted CMIP5 projections for different timeframes, statistics, emission scenarios, and climate models.
