Deserts during the day get very hot and very dry. The lack of cloud cover only increases the temperature that hits the desert. About 40 C.
Surprisingly enough, the desert gets quite cold during the night because all that warm sand loses its heat during the night due to its low heat capacity property. No heat is really contained in the air due to the lack of moisture in the air, so there is no real way to retain heat. So approximately 5 - 10 C.
