The temperature of a desert is also a defining and unique characteristic. Most deserts are warmer during the day than they are at night, and the difference in temperature is quite drastic. The average daytime temperature is 100Â°F, while at night the average temperature is 25Â°F. This large temperature difference is due to low amount of moisture in the desert air.
In addition to being extremely dry, the Sahara is also one of the hottest regions in the world. The average annual temperature for the desert is 86Â°F (30Â°C) but during the hottest months temperatures can exceed 122Â°F (50Â°C), with the highest temperature ever recorded at 136Â°F (58Â°C) in Aziziyah, Libya.he Sahara Desert is located in the northern portion of Africa and covers over 3,500,000 square miles (9,000,000 sq km) or roughly 10% of the continent (image) .
