Why is there winter in egypt, since it is a dessert?

→ Winter does not depend on where a region is.

The entire world has all the four seasons, but in some places, due to their geographic regions and climate, the seasons don't affect them in the same way as other places.

In the poles for example, there are all seasons, but their climate doesn't change much staying very cold at a pretty stable temperature throughout the whole year.
