Diving Cozumel and the Mexican Yucatan Overview

The island of Cozumel and the Yucatan peninsula attracts thousands of divers yearly. Many operators cater to experienced, savvy divers -- but some load boats with all comers. Much of Cozumel's diving is deep or drift dives. Carry a surface-signaling device (strobe, safety sausage, etc.).

The best Cozumel diving is in spring and summer. It can be rainy during the winter. Accommodations range from small, inexpensive downtown hotels to diver hangouts to high dollar hotels. There's a lot of partying, thanks to an overload of cruise ship passengers.

Many divers take day trips to the mainland by regular and inexpensive ferry to dive the freshwater cenotes -- prehistoric cave systems. Diving in a cenote can give you a new standard of visibility. For diving along the Yucatan coast, there are dive operations from Cancun south, but the diving is mainly patch reef diving.

Isla Mujeres (the Isle of Women), off Cancun, has some decent reef diving and a drift or two. Whale sharks aggregate during several summer weeks northwest of Cancun, both there and near the island of Holbox, where one can just about be guaranteed to snorkel with scores of these behemoths. The experience has recently become very popular with groups of underwater photographers.

Cozumel and the Mexican Yucatan Seasonal Dive Planner

Cozumel enjoys a fairly constant temperature of 80°F (27°C), but it rises to near 95°F (35°C) during July and August, which are also rainy months. During these months, it can get hot and humid if you venture away from the sea breeze or don't have an air-conditioned room. The rainy season runs from June through October (which is also hurricane season). Rainfall doesn't affect water visibility, as there is very little run-off. Cozumel is blessed with great visibility because of its strong currents. Cold fronts blowing down from the north can make temperatures fall during the coldest winter months, but Cozumel, because of its size and proximity to the mainland, is usually less affected than most Caribbean islands. Water temperatures vary from 75°- 85°F (26-29°C).

Travel Edition of Reef Fish Identification: Caribbean, Bahamas,
South Florida. Travel Edition of Reef Fish Identification: Caribbean, Bahamas, South Florida
by Paul Humann and Ned DeLoach

Today's airline weight restrictions not only limit the amount of dive gear and cameras you can pack for overseas trips, but also those valuable prized marine life identification books. And with spotty Internet access overseas, it's not like you can look a critter of or fish up easily online. For the divers who still want a book in their hands post-dive to look up the fishes they encounter, Paul Humann and Ned DeLoach are offering "Travel Edition of Reef Fish Identification: Caribbean, Bahamas, South Florida." It's lightweight enough to thrown in your carry-on but rugged enough to withstand frequent saltwater washings on board.

World Atlas of Coral Reefs
by Mark D. Spalding, Corinna Ravilious, Edmund P. Green, United Nations World Conservation Monitoring Center.

If there is one book that belongs in every traveling diver's library, this is it. The superb World Atlas of Coral Reefs has everything you want to know about the reefs from Costa Rica and Cuba to the Coral Sea and Cayman. The information is specific and up to date. The photos, maps and layout superb. And the price, for this 424 page, full color, hard bound volume, is a steal at $31.50

The Atlas was released in September by the United Nations World Conservation Monitoring Center to document and conserve the world's coral reefs. Clearly written with divers in mind, it's an invaluable resource for global travelers. Here's what you'll find.

  • 94 maps, including global maps of biodiversity and reef stresses, regional maps showing 3-D bathymetry and high resolution maps showing reefs, mangroves, population centers, dive centers and protected areas.
  • 280 color photographs, showing reefs, wildlife, people and places, Including 84 photographs taken from space by Shuttle astronauts.
  • Text explaining the formation, structure and ecology of coral reefs; their various uses and abuses at the hands of humans; and the techniques used in coral reef mapping.
  • Detailed texts describing the distribution and status of coral reefs in every country.
  • Data tables listing information on biodiversity, human use, and protected areas. These include statistics on coral reef area, biodiversity, fish consumption, and threats.

For example, you can learn about pollution damage to the reefs at Providenciales and the lack of human impact, as well. Or, where extensive bleaching took place in Honduras 1998. You'll read that Milne Bay in Papua New Guineas has the most extensive reef system in that country and where, in Fiji, the bumphead parrotfish and tridachna clams will not be found, thanks to overfishing.

Reef Fish ID Reef Creature ID Reef Coral ID

The Reef Set: Reef Fish, Reef Creature and Reef Coral (3 Volumes):
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. Paul and his partner Ned Deloach recently 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 Reef 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, up to 30%. Click below to buy them at Amazon:

* Reef Fish Identification: Florida Caribbean Bahamas,
* Reef Creature Identification: Florida Caribbean Bahamas, and
* Reef Coral Identification: Florida Caribbean Bahamas
* The Boxed Set of all three (you can save up to 30%)
