Climate Data Historical

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. 


  • Mean annual temperature has increased 1.5°C since 1960, with the rate of temperature increase most rapid in the winter (June–August) and slowest in the summer (December-February).
  • The frequency of ‘hot’ days and ‘hot’ nights per year have significantly increased between 1960 and 2003, with the greatest rate of increase seen in the months of September-November.
  • The frequency of ‘cold’ days and ‘cold’ nights per year has decreased between 1960 and 2003 with the greatest rate of decrease seen in the months of March-May. 


  • Mean annual rainfall has decreased at an average rate of 2 mm per month per decade, with the largest decrease seen in March-May rainfall, which has decreased at a rate of 5 mm per month per decade. 
  • In the second half of the 20th century, southern Africa has experienced a decrease in late southern hemisphere summer precipitation that has reached from Namibia through Angola, and into the Congo. This drying is associated with an increase in sea surface temperatures in the tropical Indian Ocean.
  • There is no clear trend in precipitation for the Central Plateau region; while in the Huila highlands and the central-south transition area there are indications of a decrease in precipitation and an increase in its variability.
