The variety of marine life follows the 4 season. From the tinny little and colorful nudibranch and frogfish on winter season, green turtles, hawksbill turtle, white tip reef sharks, Giant Trevally and Cuttlefish during spring and summer and the beautiful octopus and autumn. We also can spot the big ones in the island, Eagle Rays, Mantas, Hammerhead Shark and even Humpback Whales cross this water every year.
The water temperature is quite stable, in the summer (Jul. to Sep.) tops 29C while the winter (Nov. to April) drops to maximum 21C, never colder. Perfect environment so the coral reef can grow and turn the ocean of Okinawa one of the most extraordinary places in the world. The raining season goes from mid may to begging of July but the temperature is great and the dive from boat still going out despite the visibility is a bit lower than average (around 15m).
