Climate Data Historical

Malawi’s climate is as varied as the country’s topography. The vast surface water of Lake Niassa tends to have a cooling effect on the margins of the lake, where long, hot seasons with high humidity occur, along with mean annual temperatures of 24°C. Rainfall patterns are heaviest along the coast of Lake Malawi where precipitation is heaviest (averaging 1600 mm annually); the rest of the country’s rainfall ranges between 750 and 1000 mm annually. Overall, the country experiences three seasons: a cool season (May to mid-August), a hot season (mid-August to November), and a rainy season (November to April), with rains continuing longer in the northern and eastern mountains. 

Temperature

  • Mean annual temperature has increased by 0.9°C between 1960 and 2006, an average rate of 0.21°C per decade. This increase in temperature has been most rapid in the rainy summer (December to February) and lowest in the hottest season (September to November).
  • The average number of ‘hot’ days per year in Malawi has increased by 30 between 1960 and 2003. 
  • The average number of ‘cold’ days per year has decreased by 16 between 1960 and 2003. 

Precipitation

  • As year‐to‐year variability in rainfall is very high in Malawi, long-term trends are difficult to identify.
  • In 2006, wet‐season (December to February) rainfall over Malawi was markedly low, possibly causing a decreasing trend in December to February rainfall; however, evidence does not reveal consistent decreases.
