Sea of Cortez, Mexico Dive Trip


All Certification Levels


October 28th 2018 - November 5th 2018


Adventure Divers is pleased to be going back to dive the beautiful waters of the Sea of Cortez.  We have taken four groups with us over the past four years.  Everyone loves this dive trip.  The marine life, ocean topography and the shipwrecks are amazing.  The highlights of this diving adventure include:


This trip never disappoints.  On the surface you see Dolphins, Mobula Rays, Turtles and the occasional Whale.  The Sea of Cortez is an aquarium that must be explored.




Scuba Diving Sea Of Cortez (Gulf of California)

The Sea of Cortez is one of the most diverse seas on the planet, and is one of UNESCO World Heritage Sites. Jacques Cousteau, named the Sea of Cortez the "World’s Aquarium".







Heart-stopping underwater encounters await you on sites surrounding the many uninhabited wind-raked islands dotting the coastline of the Sea of Cortez. The plankton-rich currents of the Pacific along the western coast of California Sur plus the sheltered waters support whale sharks, dolphins, giant manta rays and schools of sharks such as scalloped hammerheads.

The narrow sea is home to a unique and rich ecosystem. In addition to a wide range of endemic creatures, it hosts many migratory species, such as the Humpback Whale, California Gray Whale, Killer Whale, Manta Ray and Leatherback Sea Turtle, and the world’s largest animal, the Blue Whale. There are unusual resident populations of Fin Whales and Sperm Whales that do not migrate annually. This region has historically been a magnet for world class sport fishing activities, with a rich history of sporting world records.

The Sea of Cortez sustains a large number of marine mammals, many of which are rare, and endangered. Its more than 900 islands are important nesting sites for thousands of seabirds and its waters are a primary breeding, feeding, and nursing ground for a myriad of migratory and resident fish species.

Both land based resorts and liveaboards give divers the opportunity to experience a vast array of diving possibilities, unmatched nearly anywhere else in the underwater world.

La Paz: The hub of Baja eco-tourism, affords some of the best diving in the Sea of Cortez. There is a diversity of options: a shipwreck dive, a chance to swim alongside sea lions and the likelihood of shark encounters at the seamounts.

DIVING SEASON: Year-round. The best time is late June to early November. The absolute best months are September and October, when the seas are flat, visibility peaks at 60 feet or more.

In winter, surface water temperatures drop to 65 to 70F. Seas can kick up to two to three feet, and vis drops to an average of 30 to 50 feet due to plankton blooms. On the plus side, gray whales and occasionally blue whales move into the sea in winter to feed and mate, increasing your chances of an encounter.

VISIBILITY: Summer time visibility peaks at 60 feet (18m) or more. During the winter months the vis drops to an average of 30 to 50 feet (9-15m) due to plankton blooms.

WATER TEMPERATURE: During the summer, surface temperatures hit a toasty 85F. It’s still cold enough below the thermocline that most divers opt for full 3mm wetsuits. In winter, surface water temperatures drop to 65 to 70F, so you’ll need a 5mm or 6mm full wetsuit with hood and gloves.

WEATHER: Temperatures can soar to 110F in summer, but the average is more like 95F. In the winter, expect daytime highs in the low 70Fs. The sky is usually cloudless and the sun intense, so don’t forget the sunscreen.

SKILLS LEVELS: Dives for all diver skill levels are readily available.

WHAT TO EXPECTO SEE: The Sea of Cortez has a reputation for whale sharks. During the summer and fall, divers flock to the Sea of Cortez for a chance to swim with the largest sharks in the world, which generally move south as the season gets later. Another shark also put La Paz on the map in the ’80s, when divers could see massive schools of hammerhead sharks off El Bajo and Las Animas, but unfortunately these schools have been replaced with occasional hammerhead sightings. During the winter months, mobula rays are common. Manta rays are also sighted on occasion. Another main attraction for diving La Paz are the sea lions, which frolic and play with divers, presenting amazing photo opportunities. Sea Lions are found in a number of places in the Sea of Cortez, but none beat the sea lion colony of Los Islotes.

Other Sea of Cortez marine life includes huge schools of jacks and baitballs, as well as tuna, wahoo and lots of other fish, dolphins, eels, jawfish, rays. Macro life can also be good, including nudibranchs, shells and various crabs and shrimp.
