This page presents Angola'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.
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.
Angola’s rainy season lasts from October-May and is characterized as hot and humid. The Inter-tropical Convergence Zone (ITCZ) controls rainfall as it moves between the equator and tropics, bringing rainfall to Angola as it migrates southward from the equator in October. The rains coincide with the warmest months of the year with average temperatures ranging from 22-23°C. The dry season, known as “Cacimbo,” occurs from June-September and is the coolest time of the year, with average temperatures between 18-20°C. Total rainfall decreases as you move from north to south and from east to west in Angola, with northeastern Angola receiving the most amount of rain. Located along the Atlantic Ocean, much of Angola's climate is tied to sea surface temperatures and variations in the Benguela Cold Current.
