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 range in deserts are quite high because deserts are generally very cold at night and very hot in the day time. most deserts have a mean temperature range of about 32 degree celsius.he daily temperature range in a desert varies greatly by the  location of the desert and the time of year. A typical range might  run from a low of 50 degrees F at night to â¦ a high of over 110  degrees F in the daytime.
