Obviously, if you are going to be staying on the North side of the island, Kuilima, Shark’s Cove, and Three Tables will be at the top of your list because they will all be close to where you are staying.
And, if you are staying within or near Honolulu and easy access is important, Kahe Point, Hanauma Bay, and Queens Beach or Sans Souci Beach move up your list. And, if you have a car and the time to roam around the island of Oahu, a secluded site like Kaena becomes more attractive.
Never snorkel alone. Always have a partner even when ocean conditions seem perfect. And, even in calm seas, do not turn you back on the ocean. Even on a quiet day a “freak wave” can show up. If you don’t see it coming, this sort of wave can be dangerous.
If you want to see the most fish, have access to a site like Hanauma Bay, get up and go to the beach early. It may be tempting to sleep late on your vacation, but morning is when the fish are more active and in many locations, the water tends to get cloudy later in the day due to the afternoon winds.
Look for underwater structures if you want to see marine life. These can be formations of the lava rock that is the foundation of the Hawaiian Islands, the coral that grows on it, or man-made structures. Small fish find safety within and around these areas and they are great food sources.
So, when you want to see the fish, look for structures because where there is a large sandy bottom, that area will be largely devoid of fish.
Wind and snorkeling don’t always mix very well. You may be thinking that since you are under the water that the wind does not matter. But, wind blowing across the water creates currents and the currents stir up the bottom in the relatively shallow areas that are perfect for snorkeling.
