Why dive here
Manana Island is a dive where divers can encounter blue sharks, sea turtles and sperm whales. Water ranges 25-28°C, warmest August, September, October.
Manana Island, off Oahu’s eastern coast, is a solid intermediate dive. Dropping to 18 meters, you’ll navigate lava tubes and swim-throughs that often hide white-tip reef sharks snoozing in the darker corners. The surge can pick up here, especially around the exposed side, making for an interesting ride through the volcanic topography. It's a good spot for divers comfortable with a bit of current and looking for some architectural interest.
