What is the Sahara desert rain fall per year?

The Sahara Desert receives very little rainfall, with an average of less than 100 millimeters (4 inches) per year.

However, it's important to note that rainfall is highly variable across the desert. Some areas, like the northern and southern edges of the Sahara, may experience more rainfall than others.

Here's a more detailed breakdown:

* Most of the Sahara: Receives less than 25 mm (1 inch) per year, often described as "hyper-arid."

* Northern and southern edges: May receive up to 100 mm (4 inches) per year, making these zones more hospitable for limited vegetation.

* A few areas: Experience brief, intense bursts of rainfall called "Saharan Monsoons," which can create temporary lakes and vegetation growth.

Overall, the Sahara Desert is known for its extreme dryness and is one of the driest places on Earth.
