If you are looking for the best snorkeling in Oahu, follow our tips on where to go and discover the rich marine life of Hawaii!

Best time to snorkel in Oahu

The Oahu snorkeling season is May through September. These pristine summer months provide the best conditions for the entire family to enjoy calm waters and good visibility. The average sea temperature during these months is about 82 F/27.7C. The warm water allows you to feel comfortable staying in the water and exploring marine life.

The Hanauma Bay is one of the most famous places in the entire Hawaiian Islands and probably Oahu’s best snorkeling spot which is actually a nature preserve. This popular beach stretches near Koko Head on the east side of Oahu in an old volcanic crater.

Whether you are an avid or a beginner snorkeler, expect to have a great experience here!

Hanauma bay - Oahu

Hanauma bay is a longtime favorite of water lovers, but sadly, the big number of tourists caused serious damage on the reef. In order to restore the marine life, the bay is a nature preserve now and only 3000 visitors per day can enter. There is an entry fee (7.5USD) and everyone has to watch a short conservation video that explains the important dos and don’ts on how to protect the marine life. If you are looking for the best snorkeling in Oahu, Hanauma Bay is the place you need to visit!

Tip: If you have time head to the nearby Kaiona Beach Park too where you can swim with turtles!

Sans Souci Beach

Sans Souci is a prime location on Waikiki for water lovers with the nearby Queen’s beach. These 2 places definitely provide some of the best snorkeling in Oahu: there is even a marine conservation area located right off the beaches that runs parallel the shore for quite a long distance.

Out of these 2 spots, our pick is definitely the family-friendly Sans Souci. Just a short walk away from the touristy side of Waikiki, you can experience Oahu’s best snorkeling experience at this small sandy beach with a wide variety of fish species around such as butterflyfish, parrotfish and the famous Hawaii State Fish, the Humuhumunukunukuapua`a!

This prime snorkeling location is popular among tourists and locals but try to avoid the area on days that the ocean has high waves. Go on days with flat water for ideal conditions and excellent visibility!

Kahe Point Beach Park (Electric Beach)

This exciting snorkeling spot is located between Ko Olina and Nanakuli and considered the best snorkeling in west Oahu. The nearby power station releases warm water into the ocean that attracts sea life to the bay. You will see a variety of marine species as you navigate in the clear waters. Turtles and eagle rays are daily visitors at Electric Beach, but if you are lucky, you might swim into monk seals or a pod of dolphins too!

Snorkelers who come this location need to be strong swimmers because there aren’t any lifeguards on duty. Therefore, Kahe Point Beach Park is not suitable for families with young children. However, if you are confident snorkeler, I’m sure you will spend long hours in the water since the warm current makes very comfortable swimming around.

Sharks Cove

Sharks Cove is a true gem of the island. This pretty spot on the North Shore between Banzai Pipeline and Waimea Bay offers some of the best snorkeling in Oahu.  You get supreme visibility, calm waters and plenty of marine life to explore!

While the name of this cove actually has the word shark in it, you won’t need to worry because there are shark cage operators nearby who help provide a safe environment for visitors and locals. As a snorkeler, you only get the experience of swimming with various fish species as soon as you get through the rocky area and reach the drop-off.

Snorkeling in Sharks Cove is recommended in summer only, when the water is calm. However, this spot is popular in winter too when huge waves break into, since it is the prime surfing season.
