This country is indeed a desertic one, with very low rainfall but with temperatures vacillating from very hot to cold, depending on the time of day and the season. There are some regional differences, however, to be taken into consideration:
Saudi Arabia has a desert climate. In Jeddah it is warm for most of the year. Riyadh, which is inland, is hotter in summer and colder in winter, when occasional heavy rainstorms occur. The Rub al Khali (‘empty Quarter’) seldom receives rain, making Saudi Arabia one of the driest countries in the world.
