Cenderawasih Bay is a large bay in north east Province of Papua, the western part of the bay was declared a marine national park since 2002. Cenderawasih, along with Raja Ampat and Triton Bay, makes up the Bird’s Head Seascape. Diving in this region allows you to experience some of the finest coral gardens and dramatic vertical walls, and it is the only place in the world where it's possible to spend hours diving or snorkelling with multiple Whale Sharks. Finally, there are numerous Japanese wrecks scattered around the bay from the WWII.
Cenderawasih Bay also has a few unique features in Indonesia’s pantheon of rich reefs. The bay was geologically isolated until recently, and if you look at a map you’ll see that it is still somewhat confined. Because of its isolated location this bay is protected from the Pacific currents which promote the gathering of certain endemic species. In Cenderawasih Bay you can encounter in the shallows species that normally live in deeper waters. The good muck diving will keep the lovers of the tiny and strange critters busy, they will enjoy searching for pigmy seahorses, tiger prawns and frog fish among other species.
The weather in Cenderawasih Bay is commonly rainy and stormy from February through May, the best time to dive is mid June through November every year, whale sharks are resident year round. Water temperature is between 26º - 28º C, cooler in the north area, 3 to 5mm wetsuit is reccommneded. Visibility is variable and averages 15m, this region is ideal for shooting wide angle, but there are very interesting macro subjects too. Tidal currents can be encountered on atoll and reef sites, but conditions are reliably mild where the whale sharks are found.
