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. Data for specific coordinates can be downloaded for in the Data Download page.
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).
- Mean temperature has increased by 0.7-0.9°C since the 1930's. Since the 1980's, mean annual temperature in the southern and equatorial regions of East Africa has experienced a significant increase.
- A cyclical character of rainfall has been observed.
- Since 1999, the central plateaus region has seen an increase in seasonal variability with a tendency towards a longer dry season from, 5-6 months instead of the normal 4 (June-September).
