Summers are very hot and dry; winters are mild with cooler evenings. The desert has hot days and cold nights.

Loose, long clothes in natural fabrics. A cover-up for the cooler months. Warm clothing for nights in the desert. Modest dress is advised, especially for women - upper legs and arms, shoulders and cleavage should be covered. A headscarf can be useful as extra coverage, and is essential for visiting mosques.
