Climatology
This page presents Burundi'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.
The distribution of large landforms accurately reflects that of the country's climatic diversity, resulting in an uneven distribution of rainfall in the area, despite the modest territorial dimensions of the country. Geographical areas also influence thermal variations. The higher regions experience on average colder temperatures than the lowlands. Monthly average maximum temperatures are highest at the end of the dry season (September), which varies from 25°C (Imbo region) to 15.7°C (Mugamba region). Monthly minimum temperatures are lowest during the dry season (July) and range from 23.3°C (IMBO region) to 13.9°C (Mugamba region).
