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.
The little precipitation and rain that falls in deserts is usually erratic and varies from year to year. While a desert might have an annual average of five inches of precipitation, that precipitation may come in the form of three inches one year, none the next, 15 inches the third, and two inches the fourth. Thus, in arid environments, the annual average tells little about actual rainfall.
