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.
Summers in the desert are generally hot and dry. The average highest temperature is in the upper 90s Fahrenheit, and temperatures of more than 100 are common. The average lowest temperature, on the other hand, sits in the middle 60s Fahrenheit. In some years, the temperature drops to the 40s.
