Diving Hawaii Overview

Hawaiian dive guides have developed great skill in finding the unique: On the Big Island of Hawaii, Spanish dancers, rare juveniles, and lionfish are regulars. Diving is mostly lava flow dives with little coral cover, but the tropical fish are colorful, unique, and generally plentiful.  There's access to good shore diving. Kauai reef diving is passable, but the attraction is unique trips available only in the summer.  Maui's diving is often to the backside of Molokini or Lanai, and boats leave at 7 a.m. or earlier.  Turtles are common, and occasional white tip shark adds to the fun, and the reef fish are colorful. Most reefs around Honolulu and Oahu have declined considerably, but there is some decent diving toward the north side. Nine months a year expect clear water, visibility that's usually better than the Caribbean -- around 100 feet (30m) -- and air temperatures of low 80°F (26°C). Water temperatures hit a low 70°F (20°C) in January and February when storms can last several days and cut visibility. There are plenty of condos for rent everywhere, and you'll need a car since dive boats are not berthed at hotels. 

Hawaii Seasonal Dive Planner

Temperatures in Hawaii vary little from island to island, remaining around 85°F (29°C) most of the year. From November through March, occasional cool spells drop temperatures down to 72°F (22°C) and rarely lower. Winds become more variable, and storms are more likely. Water temperatures vary from 70-84°F (21-29°C) The weather is warmest and driest from May to October, with persistent winds. There is no set hurricane season as there is in the Caribbean. The tourist off-season is from September to early December and again from mid-April to early June. Humpback season is from November to May.

Indo-Pacific Coral Reef Field Guide
by Gerald R. Allen, Roger Steene.

I was trying to pack light for a change. Surely the Solomon Sea would have good identification books aboard. Not so; the only book on the boat belonged to a fellow passenger. It was one that I had not seen before, the Indo-Pacific Coral Reef Field Guide, by two of the best fish guys around, Gerry Allen and Roger Steene. The problem was this fellow passenger kept it in a plastic baggie most of the trip and I had to beg to see it. Great book, good traveling size, and it covers everything from fish, shells, marine plants, mammals, corals, and invertebrates to sea birds and more. Now I've got my own, and it won't do you any good to beg me to borrow it. This is one of two books that I will not travel to the Pacific without. Good for travel to the Red Sea, East Africa, Seychelles, Mauritius, Maldives, Andaman Sea, Malaysia, Indonesia, Philippines, Australia, Micronesia, Polynesia, and Hawaii, it has 1,800 color illustrations in a 6x8 1/2 paperback format with 378 pages. $39.95.
