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 average temperature of the hot desert ranges from 20 to 25Â° C, but its extreme maximum temperature ranges from 43.5 to 49Â° C. As an example the Sahara desert's night temperatures during the winter months can drop to -5 ÂºC and some ares can even experience frost.he average temperatures of the cold desert in winter ranges from -2 to 4Â° C, whilst in the summer it ranges from 21 to 26Â° C. Taking Antarctica (the most extreme cold desert) as an example, its lowestt temperature was â89.2 Â°C and its highest temperature was14.6Â°C.
