Costa Rica Scuba Diving
Including the Cocos Islands
An Undercurrent Insider Report on Costa Rica Diving
The Consumer Newsletter for Serious Divers Since 1975
Overview of Costa Rica
Costa Rica is famous among experienced
divers for the big animal
action off uninhabited Cocos Island,
300 miles offshore. Here are challenging,
high-tension dives among
hammerheads, mantas, occasional
whale sharks, and other awe-inspiring
creatures. Land-based dive
operations fi nd a few big animals.
However, they're unpredictable and
the visibility is often so low you'll miss them, yet many divers like the
diving. Costa Rica has great tourist
destinations, is exceptionably safe.
Costa Rica Seasonal Dive Planner
Our suggestions for the dive season on the Pacific coast (the only decent diving in Costa Rica) may seem odd. The
best time to go is the rainy season (May through November), even though runoff can affect the water visibility.
The water clarity may be better during the dry season, but the wind blows up enough to make it almost impossible
to get out to the best dive sites, which are small islands or rock outcroppings an hour's boat ride from the mainland.
Visibility is a crap-shoot any time of the year, but even more so during the rainy season. However, even during
the wet months there is a slight chance that offshore sites can reach almost 100 foot vis, although less than forty
is more common. The best scheduling would probably be May, when the wind has died down and the rain hasn't started
yet. Water temperatures run between 75° and 85° year-round.
Cocos Island, three hundred miles off Costa Rica's shore, has a rainy season from June through
December. Some records show that the sharks are seen more often during this rainy season. Diving is year-round,
but some of the boats are pulled out of service from mid-September to October for repairs, indicating that this
is probably not the best time to dive Cocos. Also, sharks go deep in El Niño years, so these years are not
a good time to see big creatures.

Paul Humann ID Books by
Paul Humann, Ned Deloach: The three set fish, creature
and coral ID books by Paul Humann are the unparalleled sources for information
on Caribbean sea life and identification. This month Paul and his partner
Ned deLoach released updated and expanded editions of each, with scores of new
critters, even better photos, and information unavailable anywhere else. Why,
the Reef Fish Identification book, at more than 500 pages, is
20 percent larger than the previous volume, which came out in 1994. Whenever
I travel to the Caribbean, I tote all three books and spend my down hours figuring
out what I saw and where to look to find rare creatures. Paul's splendid Reef
Creature book (420 pages), covers sponges, nudibranchs, octopus, crustaceans,
Christmas tree worms and plenty more. His Coral ID book (276 pages) helps
you identify all the hard and soft corals, spawning, and even the growth on
top of corals, as well as algae and other plant life. Beginners may want to
ID only fish, but I'd recommend that all three books be part of every diver's
library. And, if you have an old set, by all means replace it. You'll be delighted
at the additions and improvements. Each book normally retails for $40, but are
discounted when you order here. And the boxed
3-volume set is available now at a bigger discount, $81.60
(June, 2004). You'll get the best prices
Amazon.com has to offer, speedy delivery, and the knowledge that a large hunk
of our profit will go to the Coral Reef Alliance, which is working to keep our
reefs alive and well. All are spiral bound, 6x9

easy and enjoyable." There are scores of flatworms, nudibranchs galore, bumblebee
shrimp, painted crayfish, pompom crabs, side-gilled sea slugs, and endless corals.

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

of fish, corals, nudibranchs, lobsters, sea stars and other critters endemic to
