Climate Data Historical

Except in the high elevation areas, its latitudinal location gives the DR Congo an equatorial, hot, humid climate with minimal variation in temperature. The DR Congo is cooler and drier in the southern highlands and cool but wetter in the eastern highlands. Average temperatures in the central basin have a very narrow range between a high of 25°C and a low of 24°C, which also applies to the northeast. The southeast range has a low of 23.5°C in July to a high of 26.9°C in October. To the north of the equator, the wet season extends from April to October with two rainfall peaks in May and October, and the dry season extends from December to February. In the southeastern part of the country, the wet season is from November to March and the dry season is from April to October. The central parts of the country receive the highest precipitation with less variability. The southeast has a distinct dry season, receiving almost no rainfall during June, July, and August.


  • The linear trend for mean annual temperature indicates a 1.32°C increase per century since 1951-1999.
  • Historical inter-annual temperatures variation within the DR Congo is largely insignificant. Internal ranges are less than 2°C with the maximum of 26°C recorded during March and February and minimum of 24°C recorded for July.


  • Mean precipitation across the DR Congo has been consistently declining since 1951. The  linear trend indicates a decrease of up to 40.79 mm/month per century.
  • The seasonal average for June-August indicates a 32.89 mm/month per decade increase with the highest declines recorded after 1990.
