eli5: why does it get so cold in the desert at night.

502 views

Let’s take the Sahara for example, it’s a lot closer to the equator, yet at night temperatures fall to -4c (25f). Yet in the uk which is a lot further away from the equator, the night temperatures are around 15c (60f) during the summer. Why is this?

It all has to do with the lack of humidity in the air. When it’s humid, we don’t sweat as quickly and the air doesn’t hold heat very well. Think of how air conditioners work, that water you see draining off the AC unit was in the air in the room it is cooling. In the desert, the air has less water in it, hence the sky looks bluer to us and feels colder when the sun is gone.
