  N'Djamena has a hot semi-arid climate (Köppen BSh) with a short wet season and a lengthy dry season. Despite the fact that the city receives on average approximately 510 mm (20 in) of rainfall annually, due to the area's very high evapotranspiration, N'Djamena still falls into the semi-arid climate category. The wet season lasts from June to September, with the heaviest rain occurring in August. The dry season essentially covers the remaining eight months. Based on annual temperatures, N'Djamena is one of the hottest major cities on the planet. In only one month of the year (August) do average monthly high temperatures fail to cross the 32 °C (90 °F) mark. The city's highest temperatures are usually seen between March and May, just before the onset of the heavier rains.
