Cabo is fascinating since it is located at the very tip of the extremely long peninsula between the Pacific Ocean and the Sea of Cortez. Diving in the Sea of Cortez can be an amazing experience for any diver, with shipwrecks, caves, reefs, and sandfalls to explore. The Sea of Cortez is considered to be one of the most fertile bodies of water in the world. This warm body of water supports over 800 species of fish, from cold-water California-related species to tropical fish and pelagics such as whale sharks, giant manta rays and hammerhead sharks.
The Cabo San Lucas Bay provides excellent diving conditions. It is a unique area for diving since several of the finest snorkeling and scuba diving sites are only a 15 to 25 minute boat ride from the downtown marina. Diving conditions are great all year. June to December offer the greatest visibility, warmest water and longest periods of calm weather. Visibility can exceed 100 feet, and the temperature averages between 78 and 85 degrees F. A deep submarine trench closely follows the bay and creates an unusual marine environment that attracts an abundance of marine life. Here the water is warm and the currents are gentle.
For those who visit Los Cabos primarily for a diving experience, all-inclusive 8 or 9 day trips are available on liveaboard schooners. These vessels take passengers to remote destinations around the Revillagegidos Islands, about 300 miles southwest of Land's End. Here you can see an abundance of marine life and no human developments.
