The Namibian rainy season generally starts in November and continues well into April. Thundershowers can be expected during December, January, February and March. Temperatures increase by about 6°C for every 1,000m you descend (or 3.5°F per 1,000ft). As a result, Namibia’s parks are hotter, especially those located in the desert. Rainfall is higher in the far north, including Etosha and the Zambezi Region (Caprivi Strip). Further south the climate is hotter and drier.
