Dive Conditions
You can dive Papua New Guinea year-round, but conditions change based on which sea you are diving. Water temperatures range from 77-86°F (25-30°C) throughout the country, and visibility usually ranges from 66-130ft (20-40m) unless you are diving at muck diving sites or sites near mangrove swamps. Water temperatures average about 79F (26C) along the edge of the Milne Bay and Coral Sea, and 88F (31C) in Kimbe Bay and the Bismark Sea.
The diving in Papua New Guinea is centered around Milne Bay in the South (Solomon & Coral Seas), Kimbe Bay (Bismarck & Solomon Seas), and Kavieng town or Lissenung Island. Divers and underwater photographers flock to Papua New Guinea to see its coral atolls and walls, WWII wrecks, barrier reefs and many other wide-angle and macro photography underwater subjects for which the Indo-Pacific is famous.
Located in Asia Pacific's Coral Triangle, Papua New Guinea lies just south of the equator and 100 miles (160km) to the north of Australia, encompassing the eastern side of New Guinea Island plus 600 smaller islands and atolls. There are 28,000 miles (45,000kms) of reef systems, so it's a destination where divers rarely come across other groups. It is home to some of the world's most spectacular scuba diving, with various dive resort and liveaboard options for every diver.
