The climate in Chad

Average daytime and nighttime temperatures

All climatic diagrams of this page are taken from the collected data from 6 measuring stations in Chad.
Weather stations at an altitude above 550m have not been included.
All data correspond to the average monthly values of the last 20 years.

Temperature records of the last 70 years

The hottest temperature measured from 1949 to May 2019 was reported by the N'djamena weather station. In May 2006 the record temperature of 46.5 °C was reported here. The hottest summer from July to September, based on all 13 weather stations in Chad below 550 metres altitude, was recorded in 1951 with an average temperature of 29.3 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 27.3 degrees Celsius.

The coldest day in these 70 years was reported by the weather station Moundou. Here the temperature dropped to 7.0 °C in January 2015. Moundou lies at an altitude of 422 meters above sea level. The coldest winter (January to March) was in 1995 with an average temperature of 22.6 °C. In Chad, it is usual to have about 4.5 degrees more at 27.1 °C for this three-month period.

Long-term development of temperatures from 1953 - 1978

In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 3 measuring points in order to have actually comparable data over as long a period as possible.

In the years 1953 to 1978 there were only these 3 weather stations in the whole country, which reported continuous temperature values (N'djamena, Sarh, Moundou). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was April 1954 with 32.3 °C. Dezember 1961 was the coldest month with an average temperature of 22.8 °C.

The average annual temperature was about 27.6 °C in the years after 1953 and about 27.0 °C in the last years before 1978. So it has dropped by about 0.6 °C. This trend only applies to the selected 3 weather stations in Chad. A considerably more comprehensive evaluation of the global warming has been provided separately.
