Climate Data Historical

The Republic of Congo has an equatorial climate with a bimodal rainfall pattern and temperature structure. March through May sees a rainy season as well as September through November. Mean monthly temperatures range from 23-26°C, with February through March experiencing the highest temperatures, and June through August experiencing the lowest. The length of the dry season follows a gradient from south to north, with southern locales experiencing a longer dry season than northern ones. The dry season extends for 3 to 4 months at 2°S and 1 to 2 months for the rest of the country. Mean annual precipitation for the Republic of Congo is 1,612 mm. The wettest areas of the country are between 1-3°S, with annual precipitation above 2,000 mm. The Inter-Tropical Convergence Zone (ITCZ) is also an important force in driving the rainy seasons as it migrates between the equator and the tropics throughout the year.

  • Mean annual temperature has increased by 0.6°C. 
  • The cities of Brazzaville and Pointe-Noire have seen average temperatures increase between 0.6°C and 0.8°C.

  • The intra-seasonal precipitation pattern during the September-November and March-May rainy seasons have fluctuated in recent years, either shortening and/or lengthening seasons.
