Let’s dive further to see what Kauai has to offer to scuba divers. Sit back, take notes if you need to, and then get your vacation plans ready for scuba diving in Kauai!

General Background on Kauai

Where is the island of Kauai located?

Kauai is also known as the “Garden Isle”, because of the massive amounts of natural green covering the land. Kauai is a volcanic Hawaiian island in the middle part of the Pacific Ocean. It is situated in the Polynesian subregion of Oceania. It lies approximately 2,450 miles away from different parts of California in the United States of America.  It is 3,900 miles east of Tokyo, Japan. Australia is a little over 4,500 hundred miles away in the northeast. It is located 72 miles (116 km) northwest of Oahu Island across the Kauai Channel. It is a part of the state of Hawaii, one of America’s states.

Are there any travel requirements that I should be aware of?

Given that Kauai is a state in America, you will need the same documentation that is needed when you are traveling to any state in the United States. At this time there are no additional COVID documentation requirements. As we are all aware, COVID specifics do change from time to time, so please double check them prior to your flight into Kauai.

What is the weather like on the island of Kauai and in the water?

Kauai touches its visitors and locals with a consistently comfortable climate. With temperature averages ranging between a mid-70 degrees Fahrenheit in the winter, and a slight rise to a mid-80 degrees Fahrenheit in the summer, it is safe to say that the weather is always nice. The underwater temperatures mirror the above ground temperatures by matching them with a warm average range of 75-80 degrees Fahrenheit (24 – 27 degrees Celsius). Rain is prevalent from November to April. So, if you want to avoid the rain, it is best to visit between the months of May till October.

When is it most crowded on the island of Kauai?

Kauai is hit with peaked tourism between the months of December through April and then again between the months of June through September. The Christmas holiday and the month of August are the busiest times of all so please remember this if you are on the look-out for a more serene get-away.

By now you are probably thinking that this island sounds familiar. If it does, let me let you in on a little secret. This is the island that was used in the filming of the first set of the Gilligan’s Island series. You know what they say, if it is beautiful enough to be on television, then it is beautiful enough to see in person.

Now let us focus in more detail on the real fun! Let’s jump right in and see what Scuba Diving in Kauai is actually like. Here are some more questions and answers to help shed some light on the deep blue water which lies below this lovely island paradise.

Where is a good place to dive on the island of Kauai?

Kauai offers a plethora of diving sites with entertainment options available for all skill levels. Let’s dive right on into the list of diving sites, you can see what each one has to offer below:

North Shore provides a great place for beginners as it is a reef on Kee Beach and Haena beach park. Anini Beach provides a sheltered lagoon for its diving and / or snorkeling visitors.

South Shore has Poipu Beach State Park which offers amazing areas as to snorkel and dive on.  

East Side gives us Lydgate Beach Park, which is a protected snorkeling lagoon, on the island.

West Side is a less visited area with a multitude of pristine views to its divers. It is here where you can find an abundance of marine life in Niihau (The Forbidden Island). This is the place where you will find manta rays and humpback whales in the winter and seals and sharks during the summer. You can also see lava tubes and underwater caves in this location.

What can I see during a typical dive on the island of Kauai?

There are many marine life habitants which live on or near the reefs, caves, and lava tubes in Kauai. You can expect to enjoy seeing the following sea life when diving on this island:

Manta Rays – These are gentle underwater giants that appear to be flying like underwater angels.

Humpback Whales – Hawaiian Islands are one of the main habitats for the humpback whales, so seeing them there is pretty much guaranteed.

Hawaiian Seals – Hawaii is a mating ground for the Hawaiian Seals, so you can bet that they will be there too.

Sharks – With numerous species of sharks in Hawaiian waters, you can see sandbar sharks, hammerheads, whitetip reef sharks, tiger sharks and more! Don’t worry, sharks are seldom a risk to divers.

Sea Turtles – the Honu – the Hawaiian Green Sea Turtles are the biggest sea turtles in the world and they are native to Hawaii.

Barracudas – With sharp teeth like sharks, these 5 feet long fish lurk in the waters so be on the lookout!
