The question is asking whether it is true that the defining characteristic of deserts is their high daytime temperatures. This is actually false, as deserts are defined as places with a very small precipitation - rainfall. In fact, the biggest desert on Earth is Antarctica, which is very cold! Some deserts are hot, for example Sahara, but not all of them.

Summer months are the wettest.
