Iraq Weather, climate and geography
Summers are very hot and dry but cooler in the mountains in the north and east. Winters are mild with some rain in central and southern Iraq but cold in the north.
Long, loose clothing in natural fabrics is advised for summer months. Medium-weights are advised during the winter.
Modest dress is advised, especially for women - upper legs and arms, shoulders and cleavage should be covered. A headscarf can be useful for extra coverage, and is essential for visiting mosques.
In Iraqi Kurdistan dress for women is very western; in the towns in the north at least half of the women do not wear headscarves and wear western fashions though this does not include short skirts, shorts or obvious cleavage.
