The Sahara Desert features a hot desert climate (Köppen climate classification BWh).The Sahara Desert is one of the driest and hottest regions of the world, with a mean temperature sometimes over 30 °C (86 °F) and the average high temperatures in summer are over 40 °C (104 °F) for months at a time, and can even soar to 47 °C (117 °F).
An area with less than 100 millimetres per year (3.9 in/year) may have remained in the Eastern Sahara however, [636] [637] although its driest parts may have received 20-fold more precipitation than today. [440] Precipitation in the Sahara probably reached no more than 500 millimetres per year (20 in/year), [638] with large uncertainty. [227]
In full contrast to the negligible annual rainfall amounts, the annual rates of potential evaporation are extraordinarily high, roughly ranging from 2,500 millimetres (100 in) per year to more than 6,000 millimetres (240 in) per year in the whole desert. [27] Nowhere else on Earth has air been found as dry and evaporative as in the Sahara region.

It lies in one of the hottest regions on the planet, in the western section of the Sahara Desert. The average annual rainfall barely reaches 45 mm (1,77 in) but is extremely variable from year to year and mostly fall between July and September, inclusively. The annual mean temperature is about 29 °C (84.2 °F).
Southeastern Morocco's desert is among the most arid places in the world and rarely experiences rain in late summer. The Moroccan government said two days of rainfall in September exceeded yearly averages in several areas that see less than 250 millimeters (10 inches) annually, including Tata, one of the areas hit hardest.
