Diving Micronesia Overview

Diving Micronesia, especially Palau and Truk, is near the top of most divers' lists. Most divers head to Palau, where big fish abound. The Blue Corner is among the world's best high voltage dive sites. Visibility can exceed 200ft (60m), while currents range from nil to dangerously strong -- so use a reef hook and bring your safety sausage. Long day-boat rides to the best diving weave through calm waters and past magnificent rock islands, but there's the potential for rough seas on the outer edges. Most divers prefer liveaboards. Marine biodiversity is among the greatest in the world, but coral bleaching and commercial fishing are taking their toll. There's WWII wreck diving in the lagoon at Koror, but visibility can be poor.

Wreck diving mavens head to Truk (properly called Chuuk) and the world's most diverse wreck diving on a Japanese freighter fleet sunk by Americans during WWII.

Most wreck dives, other than on the superstructures, exceed 80ft (24m) deep, but they're great even without penetration. The wrecks are starting to suffer, and many artifacts that should have been left alone have been purloined, but the ships are festooned with coral, and most all the unique reef fish of the Pacific have made them home.

When diving Truk expect calm water, occasional poor visibility, and hot weather. Both destinations are such a long haul that divers usually stop at a second island to amortize their trip costs. Yap has been the traditional stopover, known for manta encounters, but the diving in Kosrae and Pohnpei may be better choices.

If you want to dive a fleet of obsolete wartime naval ships sunk by an atomic blast in 1945, get to Bikini Atoll in the Marshall Islands. Every vessel there has a history and the USS Saratoga is upright and the largest diveable aircraft carrier not intentionally scuttled.

Micronesia Seasonal Dive Planner

Air temperatures uniformly remain in the 80°F (29°C) year-round. For land travel, there's little difference between the wet and dry season, although January through March is considered the most comfortable season because of lower humidity and slightly cooler temperatures. Although visibility is slightly reduced by run-off during the July through October monsoons, the wind is also milder during this season, producing flatter seas. Water temperatures remain around 85°F (29°C) year-round. Typhoons are most frequent between August and December but are rare in Palau.

Dive Sites of the Great Barrier Reef Dive Sites of the Great Barrier Reef
by Neville Coleman.

With 2900 reefs in 220,000 square miles, the enormous Great Barrier Reef has incredible dives -- and some very ordinary ones.

This 176 page book, with good maps and scores of colorful photos, describes the significant sites, the topography and the critters, then rates and ranks them so you can pick the best. Don't even consider a trip to Australia without consulting this. $24.95

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.
