There is truly so much to see in Milne Bay. Being within the Coral Triangle, there have been many studies proving that marine biodiversity here is close to the highest in the world.
For those who love the weird and wonderful critters, pygmy seahorses, rare Rhinopias scorpionfish, all manner of eels, octopus, cuttlefish and frogfish can be found here and more. For those who like bigger creatures, there will be no disappointment at Milne Bay. Cleaning stations for manta rays can be found at Samarai Island.
At the outer reefs, you could even see a great hammerhead shark. Sharks are ever present and expect to see whitetips, blacktips and grey reef sharks. Whale sharks have also been known to appear around Milne Bay and even minke whales have been seen passing by.
You can dive Papua New Guinea and the Solomon Sea year-round, but conditions can vary by month. For example, September is manta season in Milne Bay, and May to August can bring choppy surface conditions. Rain during May to August can make visibility poor at the muck diving sites.
Otherwise, at the coral reefs, visibility is always good, averaging around 66-100ft (20-30m). Water temperature sit at about 82˚F (28˚C), but can dip to 77˚F (25˚C) during the rainy months.
