Saudi Arabia Geography & Map
Saudi Arabia is a relatively large country offering vast contrasts of climate, scenery and relief from the temperate, rainy heights of the rugged southwestern mountains to the dry, daunting wastes of the great Rub' al-Khali desert.
Throughout the country temperatures drop significantly at night. Even day-time temperatures can be rather cool, depending upon the location and the season. Travelers are, therefore advised to take some heavy clothing with them in winter as well as the usual light apparel.
