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.
As weâve said above, rainfall is low, averaging only 150mm per year. Itâs very unreliable and can fall at any time of the year. Temperatures in the desert zone average 36-39C in summer and 18-24C in winter. However, summer temperatures of 50 C have been recorded. Although this area is one of the hottest on the Australian continent in the summer, it has a temperate winter.
