During the summer, from May to September, when the ocean is flat, O‘ahu’s North Shore beaches are an amazing place to snorkel. With a mix of rocks, reef, sand, calm waters, and favorable winds, just about anywhere you jump in the water will have some interesting underwater topography, coral, and marine life.

Pupukea-Waimea Marine Life Conservation District

Established in 1983 to conserve and replenish marine species at Three Tables and Sharks Cove, the reserve was expanded in 2003 to include Waimea Bay, covering 100 acres of coastline about a mile long. Fishing or the taking of any marine species is strictly prohibited in the area. Look for wrasse, surgeonfish, reef squid, puffer fish, the spotted eagle ray, palani, unicorn fish, harlequin shrimp, and frogfish, just some of the creatures that inhabit the area. Waimea Bay is also known for pods of spinner dolphins that frolic in the middle of the bay.

There are boat dives and shore dives available on the North Shore. The shore dives explore Three Tables and Sharks Cove, where there are flourishing reefs teeming with endemic fish and lava tubes, caverns, and walls to explore. The boat dives provide access to the extraordinary underwater topography and pristine offshore reefs of the North Shore Beaches: Atlantis is an area full of trenches, valleys, walls, and lava tubes, and Cathedrals has rock formations, reefs, and caverns where turtles, eels, and whitetip reef sharks are common; Grand Canyon is a drift dive along the North Shore Beaches where you’ll find sponges hanging from the ledges and trevallies and rays in the deep water; two reef sites, Nanny’s Reef and Nautilus Reef, are 40-foot dives with a plethora of marine life. Diving the North Shore during the winter is contingent on the size of the surf.
