How much rain falls in the Sahara desert 10 years?

The amount of rainfall in the Sahara desert can vary significantly from year to year, and it can be difficult to provide a precise measurement for a 10-year period. However, according to data from the United Nations Environment Programme (UNEP), the average annual rainfall in the Sahara desert is approximately 100 millimeters (mm) per year. This means that over a 10-year period, the total rainfall in the Sahara desert would be approximately 1,000 mm.

However, it's important to note that rainfall in the Sahara desert is not evenly distributed throughout the region. Some areas, such as the northern fringes of the desert, may receive more rainfall than others, while some areas may receive very little rainfall at all. Additionally, rainfall patterns can vary from year to year, with some years experiencing more rainfall than others.
