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.
In the case of hot deserts the temperature range from highs of 43.5 to 49Â° C to minimum temperatures down to -18Â° C. The hottest ever recorded was 57.8Â° C. Cold deserts like the Antarctic have temperature ranges from an average of -70 Co during the winter months and -35 Co in the warmer months.The lowest temperature was -89.6 Co was recorded on 21st July, 1983, at Vostok Station.he average temperatures of the cold desert in winter ranges from -2 to 4Â° C, whilst in the summer it ranges from 21 to 26Â° C. Taking Antarctica (the most extreme cold desert) as an example, its lowestt temperature was â89.2 Â°C and its highest temperature was14.6Â°C.
