Conditions depend on the spot and the season, and they are not guaranteed on any given day. At Hanauma Bay, visibility is usually best at low tide and early in the day, before snorkelers stir up sediment. Ocean Safety lifeguards serve the preserve.
On the North Shore, the Department of Land and Natural Resources (DLNR) says the water in the Pūpūkea district is generally calm from about May through October, but surges are possible. The same agency says that during the winter months, current and wave conditions become extremely dangerous in all areas of the district, including the tidepool area.
At Shark's Cove, the tidepools with schools of fish are popular for snorkeling during high tides. The City's Ocean Safety chief says the area presents hazards that can change quickly. Check the NWS marine forecast and the surf conditions for the day before you choose a North Shore spot.
How do you get to each spot, and where do you park?
Shark's Cove has a parking lot at Pūpūkea Beach Park, reached by the park's access road.
To reach Three Tables, take Kamehameha Highway (Hwy 83) from Haleʻiwa or Kahuku to Waimea. Snorkeling is good around and just outside the tables area.
Plan your parking before you go, and leave extra time for the North Shore. Waimea town separates Pūpūkea and Waimea Bay Beach Parks by a small residential section.
