In Oman visibility varies throughout the year from 10 to 40 m and can be affected by a variety of factors, including nutrient rich water. This lowers visibility but increases marine life abundance.
Water temperatures vary from around 18 to 22 centigrades in winter and 29 to 31 centigrades in summer, ideal for diving and snorkeling.
With the exception of the monsoon season in the south, you can dive in Oman all year round.
Required diving skills are entry level and up. Drift Diver, Wreck Diver and Cavern Diver specialty course certifications may be useful and can be taken here.
3 mm suits are adequate during the warmer months and 5 mm preferable during the cooler season. While equipment is available for hire, it is advisable to bring as much personal gear as possible.
Most Omani islands are fossil limestone formations, consisting of around 35 to 55 million year old Eocene limestone and marl. These stones were originally part of the sea floor but are now exposed on the surface due to uplift and change in sea levels. They are composed of the shells of marine organisms such as bivalve shellfish, coral and algae, deposited in a shallow marine environment.
Situated 1000 km south of Muscat, the Dhofar region offers an invigorating lush temperate climate in stark contrast to the rest of the country. The monsoon brings the rain from June to September, creating a unique lush green landscape set against a dramatic backdrop of the mountains. The steep coast enables larger ocean dwellers such as whales, whale sharks and groups of seasonal hammerheads to pass in the open sea. New dive sites are being discovered all the time.
