Undersea World

The volcanic activity that formed the Hawaiian Islands has left a fascinating seascape of arches, craters, bommies, and lava tubes to explore.  Many sites are rich in corals, especially hard corals.

About 20% of the fishes are endemic, with many examples in the butterflyfish and angelfish families.  Otherwise, there is a great variety of macro life that includes the Hawaiian lionfish, frogfish, moray eels, nudibranchs, Spanish dancers, lobsters, conchs, harlequin shrimp, octopus, spotted boxfish, sea cucumbers, and scorpionfish.  Commonly observed colorful reef tropicals are squirrelfish, wedgetail triggerfish, porcupine puffers, orange-band surgeonfish, unicornfish, peacock razorfish, peacock groupers, Moorish idols, yellowtail coris, parrotfish, trumpetfish, and many others.

There is also no lack of megafauna with large trevallies, spinner dolphins, green turtles, grey reef, whitetip reef, oceanic whitetip, tiger, and hammerhead sharks, eagle rays, monk seals, and seasonal humpback whales in the winter.  Mantas are also common and there is a great spot to see them on night dives, as well.

Seasons and Conditions

Diving is possible on the Big Island all year.

• The average daily air temperature highs range from 81°F (27°C) in February to 87°F (30.5°C) in August and September.
• Water temperature runs from lows of 76°C (24°C) in December through March to highs of 80°C (27°F) in August through September on the surface.  Thermoclines are possible.  3-5mm wetsuits are suitable when the water is at its warmest.  Some divers may opt for 6-7mm of insulation when it is coolest
• There is substantial rain all year with a drier season from May through September.  Rains are usually of short duration and not intense.
• Current can be strong at times on some sites.  In the summer months, it is windier and surface chop can be greater.
• Visibility is typically 50-100 feet (15-30 meters).

Best Hawaii Liveaboard Scuba Diving – Kona Aggressor II

The “Kona” in Kona Aggressor II represents Kona, on the big island of Hawaii. Kona Aggressor dive safaris focus on the dive sites on the west side of this island.  Diving is good all around the Hawaiian Islands, but this area arguably has the best.  There are 22 primary dive sites on the Aggressor cruise (see map below) and most of the diving is suitable for open water divers.

Somewhat surprisingly, there is only one major liveaboard company operating in Hawaii, the Aggressor Fleet.  Certainly, it is possible to charter other excellent vessels of various sizes and configurations, but that method tends to be very expensive.  The very reasonable Aggressor rates are even more favorable when compared to paying for a decent Hawaiian hotel and trying to get in a good 5-6 dives a day, including night dives, on top of accommodation fees.  This is one of the best all-inclusive scuba vacations on a very comfortable boat that has been in operation in this location since 1989.  The food and service are outstanding and for a maximum of 14 divers, it can become a close-knit and personal experience.

People have a great time on this Aggressor liveaboard doing up to 5 or 6 dives per day and enjoying the camaraderie, food, and service in between.  The Aggressor motto is “Eat.  Sleep.  Dive.”

Hawaii Transportation, Hotels, & Diving Services

Transportation

• Air – There are two major airports on the Big Island.  The busiest is Kona International Airport in Kalaoa on the west coast and the second is Hilo International Airport on the east coast.  They both connect to island destinations and to each other.  Kona handles flights to/from many western continental US locations and Japan.  Hilo has a connection to LA as well as the local islands.
• Boat – There is currently no inter-island boat or ferry service.
• Local public bus service is very limited but available.  Tour buses can be arranged.
• Rental of bicycles and scooters/mopeds is a possibility for transportation if you’re staying in one area.
• Hitchhiking is convenient and very easy with the aloha spirit permeating the roadways.
• Car rental makes movement around the long distances of the island much more fruitful and convenient.  You are best advised to make a reservation early online as they tend to get booked up months in advance.  Major agencies are available as well as Craigslist for less immaculate models.  4-wheel drive vehicles are available from some agencies.  Harper Rentals has them that are authorized to go off-road.

Hotels and Dive Shops

On the Big Island, there are hundreds of lodging options from $79 per night on up for your time before and after the cruise or if you would just like to spend some time in this fantastic location.  If you would like to do some shore-based diving, there are dozens of dive shops in operation offering a full range of services that include equipment rental, diving certification classes, dive guides, and boat tours.

The website linked below has the details for the lodging and can arrange a booking.  You can easily find the location on the map provided on their site.  The rates are guaranteed to be the lowest and it is free to cancel or change dates.
