Once the top layer is cooled down, and no source of heat remains in the air, the subsequent layers of air also start getting colder. So, if you are in a tropical desert, there will be a sharp drop in temperature but you will not be freezing.
Can a desert freeze at night?
Summer nights might be little warm but winter nights have temperatures below the freezing point. The heat from the sky gets radiated into space and hence the temperatures plummet to nearly 40 degrees Fahrenheit during night times. The desert animals and reptiles come out during night times.

Can ice form in the desert?

What is the hottest place on earth?
Death Valley holds the record for the highest air temperature on the planet: On 10 July 1913, temperatures at the aptly named Furnace Creek area in the California desert reached a blistering 56.7°C (134.1°F). Average summer temperatures, meanwhile, often rise above 45°C (113°F).

Why Do We Get So Hot When We Sleep? The reason people “sleep hot” has a lot to do with design. Our core temperature drops by a couple of degrees during the night, shedding heat into the surrounding areas, and certain sheets and mattresses trap the heat and moisture around us.
Why is the Sahara so dry?
The high position of the Sun, the extremely low relative humidity, and the lack of vegetation and rainfall make the Great Desert the hottest large region in the world, and the hottest place on Earth during summer in some spots.

Why is it colder at night?
As we all know, the sun will heat the Earth’s surface during the day. Then at night, the sun is on the other side of the globe, so temperatures cool back down.
How hot can a human survive?
How does – or doesn’t – your body cope in extreme situations? The maximum body temperature a human can survive is 108.14°F. At higher temperatures the body turns into scrambled eggs: proteins are denatured and the brain gets damaged irreparably.
