Your Guide to Diving Tonga

All of Undercurrent's information on diving Tonga, including articles, reader reports, Chapbook sections, ...

Diving Tonga Overview

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, and whale season attracts the adventurous. 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 the individual climate doesn't differ all that much. The average air temperature in the northern islands is 80°F (27°C) while the southern islands average 74°F (23°C), ranging from a cool 59°F (15°C) in the winter (July to September) to a high around 85°F (29°C) the summer (December to April). By November, the water temperatures reach mid 80°F (29°C), and then drop down as low as 70°F (21°C) 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 from November to March.

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.
