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.
But the average annual amount of precipitation is 250 mm to 500mm. But the annual precipitation is different in other hot deserts. Cold Deserts average temperatures are -2 degrees Celsius to 26 degrees Celsius. Itâs colder in winter but much hotter in the summer. But the extremes of the cold deserts are a lot more different like the North Pole and the South Pole.
