The coldest temperature in the Sahara desert is 36 degrees. Well, it depends on where in the desert, but it can reach below freezing. Its colder nearer to the ocean and warmer towards the center of the desert.
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.n the case of hot deserts the temperature range from highs of 43.5 to 49Â° C to minimum temperatures down to -18Â° C.
