What is the climate of Sahara desert?

The Sahara desert generally features an arid climate. The Sahara desert is one of the hottest regions of the world, with a mean temperature over 30 °C (86 °F). Variations may also be huge, from over 50 °C (120 °F) during the day during the summer, to temperatures below 0 at night in summer. The Sahara receives very little rain in the Inter-Tropical Convergence Zone which moves up from the south. Wind and sand storms occur as soon as early spring. Local inhabitants protect themselves from heat, cold and mostly wind and sand by covering their heads, such as the cheche worn by Tuareg.
