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.
The temperature in the desert can change drastically from day to night because the air is so dry that heat escapes rapidly at night. The daytime temperature averages 38Â°C while in some deserts it can get down to -4Â°C at night. The temperature also varies greatly depending on the location of the desert. The Mojave Desert is found at elevations of 2,000 to 5,000 feet, and is considered a high desert.
