Climate Data Historical

Togo's climate varies from tropical to savanna. The southern part of the country is humid, with temperatures ranging from 23°C to 32°C. In the north, temperature fluctuations are greater—from 18°C to more than 38°C. Rainfall in the south of the country comes in the form of two seasons: the first between April and July and the second between September and November. The dry desert winds of the Hamattan blow south between November to March, bringing cooler, drier weather, and periodic droughts to the north of the country. Key historical climate trends are summarized below:

Temperature

  • Togo's mean annual temperature has increased by 1.1°C since 1960, an average rate of 0.24°C per decade. The rate of increase has been most rapid in the northern regions between April-June, around 0.31°C per decade.
  • Daily temperature data indicate that the frequency of ‘hot’ days and nights has increased significantly in all seasons. 
  • The average number of ‘hot’ days per year in Togo increased by 57 (an additional 15.5% of days) between 1960 and 2003, most strongly between September-October, during the second rainy season.
  • The average number of ‘hot’ nights per year increased by 79 (an additional 21.5% of nights) between 1960 and 2003, again most strongly during the second rainy season between September-October.
  • The frequency of cold days and nights has decreased significantly since 1960 in all seasons.
  • The average number of ‘cold’ days per year has decreased by 21 (5.8% of days) between 1960 and 2003. This rate of decrease is most rapid in summer (June-August) when the average number of cold summer days has decreased by 2.5 days per month (8.1% of summer days).
  • The average number of ‘cold’ nights per year has decreased by 14 (4.0% of days), and this decrease is most rapid in June-August when the average number of cold nights has decreased by 2.8 nights per month.

Precipitation

  • Rainfall in Togo varies on both decadal and inter-annual scales, making long-term trends difficult to pinpoint. Rainfall levels were particularly pronounced in the 1960's and decreased to low levels in the late 1970's and early 1980's, as in much of the Sahelian region. Overall, this has led to a decreasing trend of an average 2.3 mm per month (2.4%) per decade from 1960 to 2006.
