Best Scuba Diving Kauai
Background
BackgroundKaua’i, known as the Garden Island, with a more sandy coastline than any other Hawaiian island, has a population of 67,000 and is situated 105 miles (168 kilometers) across the Kaua’i Channel from Oahu.
Originating from volcanic activity 5,000 years ago it is geologically the oldest of the islands. The highest peak is Mount Kawaikini at 5,243 feet (1,598 meters) and the climate is tropical with one region of the island receiving 460 inches (11.684 meters) of rain per year.
Captain Cook first landed in 1778 but Kaua’i has not been the target of economic exploitation to the extent of the other major islands. However, today tourists number more than 1.3 million per year with only 3% of the population involved in agriculture.
The natural beauty of Kaua’i has been recognized by its inclusion in 70 Hollywood movies. The biggest city is Kapa’a in the east with a population of 10,000. Number two with half that number is Lihu’e, the site of the airport in the southeast. Other towns are Po’ipu in the south, Princeville in the north, and Waimea in the west.

Undersea World
The volcanic origin of Kauai has left an intriguing undersea topography of lava ridges, caves, arches, walls, swim-throughs, craters, and pinnacles to explore on dozens of dive sites.
While not as rich in colorful soft corals as some other sites around the world at the same latitude, there is a nice encrusting life of hard corals, and other invertebrates including black coral, sponges, and gorgonians in places.
The other marine life is quite diverse with 25% of it endemic along the Hawaiian chain with 680 species of fish, 420 of which are inshore.
Megafauna highlights to look for are green turtles, dolphins, monk seals, humpback whales, groupers, whitetip and grey reef sharks, silky sharks, sandbar sharks, brown stingrays, and pelagics like tuna.
Among the macro marine life and reef tropicals, there are helmet conchs, lobsters, crabs, octopus, moray eels, longfin anthias, damselfish, blue-striped grunts, wrasses, parrotfish, triggerfish, surgeonfish, snappers, and bandit angelfish.
On trips to Niihau Island to the west hammerheads and mantas are often sighted.
Seasons and Conditions
Diving is possible on Kaua’i all year.
- The average daily air temperature highs range from 78°F (26°C) in January through March to 85°F (29°C) in August and September.
- Water temperature runs from 70-77°F (21-25°C). 3-5mm wetsuits are suitable when the water is at its warmest. Some divers will opt for 7mm of insulation when it is at its coolest
- There is substantial rain all year with a drier season from May through September.
- Current can be strong with more on the east and west side sites. The north and south side sites also have the possibility of moderate to strong currents at times. Outside the surf zone, the surface chop is generally moderate with more likely in the winter months.
- Visibility is typically excellent in the 50-70 foot (15-21 meter) range sometimes extending to 100 feet (30 meters).
There are conditions suitable for all levels of diver. At least 26 dive shops operate on Kaua’i providing a full range of diving coursework, equipment rental, guiding, and boat cruises.
Hawaii Liveaboard
There is not a liveaboard that directly cruises the Kaua’i dive sites, but there is one that dives on the big island. Here is my review and a link to that liveaboard:
