The UAE lies in the arid tropical zone extending across Asia and North Africa. Climatic conditions in the area are strongly influenced by the Indian Ocean, since the country borders both the Arabian Gulf and the Gulf of Oman. This explains why high temperatures in summer are always accompanied by high humidity along the coast. There are noticeable variations in climate between the coastal regions, the deserts of the interior region, and mountainous areas. High temperature is accompanied by high humidity in the summer and there is noticeable discrepancy between the coastal areas and the inner desert regions which is the most dominant feature of UAE geography. Temperature averages 37.7C in July and humidity goes up to saturation. The temperature range widens as we go deeper into the desert. The weather becomes moderate in the mountainous areas.
The UAE, like all other countries on the dry tropical zone, suffers lack of rain . The amount of rain fluctuates from one year to the other as well as from one region to the other. It is abundant in the emirates of Fujiirah and Ras Al Khaiyma due to their geographic location and their proximity to mountains.
