Do deserts cool off at night?
The main reason why temperatures drop in deserts during the night is because of sand: it is not able to hold heat, and it turns the entire desert hot. Deserts are extremely dry places with almost no humidity, so the heat can’t be retained during the night. Not all deserts get cold during the night.
