Wrapped around the eastern end of the Arabian peninsula, Oman is influenced by both the Arabian Sea and Persian Gulf. The nation's most populated area, along the Gulf of Oman coast, offers truly world-class sultriness. From May through September, the coastal strip is more hot and humid than Miami ever gets. Nights regularly hang above 30°C/86°F. The often-dusty shamal winds of the Persian Gulf normally diminish as they reach Oman. From November to March, the coast sees ample sunshine and plenty of warmth, with only a stray shower or storm every week or two. The lower Arabian Sea coast around Salalah gets some cloud and rainfall during the summer on southwest monsoonal winds. Perhaps once a decade, a tropical cyclone threatens Oman from the Arabian Sea. As in Yemen, the higher terrain is more moist than the lowlands.
