It's as big as the continental United States, but covered in sand. If you like to dig your feet in the sand, then the Sahara Desert is the place for you. Watch out though - it's hot! Temperatures range from 122 F to below freezing in the winter. Sand dunes can reach over 189 meters tall or be flat for miles and miles.
The Sahara desert is quiet expansive, as such the mean temperature varies quite a bit, coastal areas of the desert being more temperate. In summer the day temperature can â¦ range from 40 to 50 degrees Celsius At night the temperatures can reach 0 degrees Celsius or lower! The mean average temperature (that is to say the average temperature of all the days in the year) is over 30 degrees Celsius.
