Milne Bay is vast with a great variety of dive sites. The area boasts superb muck diving, airplane wrecks from World War II, stunning drop-offs, towering pinnacles and colorful coral gardens. For land-based diving, pick from resorts and dive operators located in Alotau or others along the north coast of the bay. Otherwise, there are liveaboard diving vessels which frequent this vast area.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, especially 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.For critter hunting, head to the north coast of Milne Bay for muck dive sites like Dinah’s Beach or the Tawali House Reef. These sites are sheltered and all that is needed is good buoyancy. Also in the north coast but at the outer reefs, you will find drop-offs where there could be stronger currents and surface swells. One of the best plane wrecks in the whole of Papua New Guinea, a B-17 Bomber called the Black Jack, is also in the area but lies at a maximum depth of 150ft (46m). To the south of Milne Bay, visit Samarai Island which has an easily accessible manta ray cleaning station and a wonderful wharf to dive.
