How much rainfall does a desert get? A desert is defined as an area that receives on average less than10 inches (250 mm) of precipitation per year. Some desert areasreceive virtually no rain at all for years.
As a result, the Namib receives an average annual rainfall of only 2.5cm (1in). The sand dunes of the desert receive moisture from the atmosphere, in the form of fog. Every 10 days or so, a dense night fog rolls inland for a distance of 80km (50mi) or more, shrouding the coast and much of the desert. The fog condenses into a thick dew, creating an annual average of 4cm (1.6in) of moisture. Temperature in the Namib reaches a high of 66Â°C (150Â°F) in the middle of the day. Gravel and rock plains extend north from the Kuiseb River. The treacherous coastal waters of this region regularly snare ships, such as the Dunedin Star (1942) and the Shawnee (1976), and cast them up on the shifting sands.
