You already know about the clouds from the other members. But it is also an issue of altitude. Most deserts are below sea level. There's a lot of science involved with it, but long story short, the heat rises out of the desert and dissipates in the thin air while the cool sinks down into what is seemingly a "bowl" shaped land.

It is due to the absence of water vapour in the air over the deserts.If there is water vapour in the atmosphere, it will trap the outgoing heat in the night and prevent it from escaping to space thereby keeping the air above the ground comparatively warmer.This will prevent the ground from losing more heat.
On the other hand if the air is very dry,(which is usually the case with the deserts),the rate of cooling will be more in the night as there is nothing(like moisture) to prevent the heat from escaping into space and the ground becomes very cold.

During the day the sun heats up the air and ground. Since deserts have little cloud cover, the heat is dissipated into the sky. Since there is not cloud cover to reflect the heat back to the ground it just dissipates into the atmosphere and is lost. Sleep without a blanket and you will understand.

Radiation cooling
No nice clouds to prevent the energy being radiated to space

most often due to the lack of cloud cover and the insulating heat it brings
