The climate of Saudi Arabia is marked by high temperatures during the day and low temperatures at night. The country follows the pattern of the desert climate, with the exception of the southwest, which features a localized tropical savannna climate around the Fayfa Mountains due to summer rainfall dominance rather than the spring rains seen further north in Al-Baha, Taif, and Asir. Rainfall averages within Saudi Arabia do not regularly exceed 125 mm, except for in the southwest where annual rainfall averages 400-700 mm with warm to hot summers and cool to cold winters of (-2-17° C).
