Mauritania is mostly covered with desert, with only its western regions around the coast of Atlantic Ocean having some vegetation. There are some oasis in the desert regions. Since it is a desert, there are large shifting dunes forming temporary ranges. The average elevation is around 460 m (1,510 ft) above the mean sea level.

The average temparature is 37.8 °C (100.0 °F), while during the night it reaches 0 °C (32 °F). Due to the geography, the inhabitants historically, have been nomadic. In modern times, people have migrated to urban centres during the drought in 1970 and 1980. There are a few sedantary cultivators, who are located only in the Southern regions of the country. Research has indicated that the Saharan movement has resulted in reduction of rains in the region from the 1960s, when it received close to 250 mm (9.8 in) of rainfall.
