I cite the following post that I've pasted below... 1.5 Liters is what he says: Obada Barry, DMD.
Seasons have a much greater impact in the interior. In the Sahara Desert, summer temperatures often exceed 104ÂºF/ 40ÂºC in summer, but may fall to near freezing during winter nights. In terms of rainfall, the northern part of Morocco is considerably wetter than the arid south (especially along the coast).
The Sahara desert is the third largest desert in the world. It is  also the world's hottest desert. The countries it covers include  Algeria, Chad, Egypt, Libya, Mali, Mauri â¦ tania, Morocco, Niger,  Western Sahara, Sudan, and Tunisia. The two largest deserts in Africa are the Sahara in northern Africa and the Kalahari in southern Africa.       The Sahara Desert covers 3,500,000 miles. It is the largest desert in the world. The name Sahara comes from the Arabic word for desert.
