Overview of Tonga

This island grouping, with all the beauty of the classic south Pacific, lies 600 miles to the southeast of Fiji and can be reached via Hawaii, Fiji, or New Zealand. There are few dive operations here, but reports suggest that the diving is good. Tonga is seeking more tourism, although it has been slow to develop....

Tonga Seasonal Dive Planner

Tonga's 170 islands cover a long distance in latitude, but their climates don't differ all that much. The average air temperature in the northern islands is 80°, while the southern islands average 74°, ranging from a cool 59° in the winter (July to September) to a high in the lower 80s in the summer (December to April). By November, the water temperatures reach the mid 80s, then drop down as low as 70° during their winter months. December through April is also the rainy season, with the most rain falling in February and March. Tonga is prone to tropical cyclones, getting an average of a couple each year. They usually develop in the south and move north, meaning that the odds go up in the northern islands. Cyclones happen as late as May but are most likely during November to March.

Coral Reef Animals of the Indo-Pacific
by Terrence M. Gosliner, David W. Behrens, Gary C. Williams.

At last -- a just-published, complete guide to help you identify the uncountable variety of weird critters you'll see on any Indo-Pacific dive, complete with full-color photo of 1,100 species. About Coral Reef Animals of the Indo-Pacific, Chris Newbert says, "This invaluable new book makes identification easy and enjoyable." There are scores of flatworms, nudibranchs galore, bumblebee shrimp, painted crayfish, pompom crabs, side-gilled sea slugs, and endless corals. Marine biologists Terry Gosliner, David Behrens, and Gary Williams cover the reefs from the Solomons to Sipadan, from the Maldives to Maui, from Palau to Papua New Guinea. They provide good notes to help you find and identify each critter. Indispensable for any Indo-Pacific trip. Paperback, 8x110, 314 pages, $45.00.

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.

Sea of Cortez Marine Animals by Daniell W. Gotshall, Daniel Gotshal. It's just the book you'll need to identify critters anywhere along Mexico's Pacific Coast, all the way to Panama. Any other ID book just doesn't cover the creatures here. Dan Gotshall, a marine biologist with 34 years research experience, has more the 250 photos of fish, corals, nudibranchs, lobsters, sea stars and other critters endemic to these waters. For each animal there are tips how to identify and where to spot it. Paper, 110 pages, $20.95
