The hottest summer from July to September, based on all 14 weather stations in Niger below 500 meters altitude, was recorded in 1987 with an average temperature of 30.4 °C. This average temperature will normally be measured every four to six hours, thus also including the nights. Normally, this value is 28.9 degrees Celsius.

Data basis and methodology

The data from the individual measuring stations are based on the archives of the German Weather Service, individual values averaged and supplemented by own elements. In order to determine a representative national average, average values were first calculated for each part of the country, which were then summarized at the national level. Thus, if a disproportionate number of weather stations are located in a small area, their number does not affect the national average.
