marine life los cabos

No matter what time of year you want to visit Los Cabos, Mexico, there is an unbelievable amount of marine life waiting for you on your dives. The biodiversity is on another level. You can see everything from whales and apex predators like hammerhead sharks to nudibranchs, turtles, and huge schools of snapper and jacks, all within a short distance from Cabo San Lucas proper. There are even unique sightings like the enormous Mobula ray schools (which can draw in hunting orcas!)

Why is Cabo San Lucas so abundant with wildlife?

Cabo San Lucas is at the tip of Baja California and benefits from the mixing of the Pacific Ocean and the Sea of Cortez, making it the perfect balance of nutrients for tropical creatures, while keeping the water cool enough as a safe haven for migratory pelagic animals.

The other side of the Los Cabos success story is the conservation effort. Marine sanctuaries and the UNESCO World Heritage site El Arco have been protected for decades, making it a safe space for creatures to call home. Here you will see large quantities of different species and animals that have been able to grow large due to their protected status.

Diving in Cabo San Lucas is breathtaking all year round

It’s always a good dive day in Cabo San Lucas. Marine life regulars, regardless of the season, include sea lions, turtles, nudis, frogfish, sea horses, white tip reef sharks, hammerheads, dolphins, bull sharks, goat fish, puffers, and jacks, along with the standard tropical creatures like angelfish, snappers, lobsters, moray eels, rays, and many more.

When choosing your trip date carefully, you could also have a chance to see whale sharks, whales, sharks (mako, blue, silky, bull), and Mahi Mahi, to name just a few! The fact that there are so many unique seasons of marine life in Los Cabos means that it is the perfect place to visit year after year to see everything there is to offer.

The Winter time is for the whales

Around here, we refer to our friendly migratory whale population as gentle giants. Humpbacks make a show on the surface where you can see them on a standard whale-watching tour or you could even get lucky to catch a glimpse of them underwater at the Gordo Banks dive site. Grey whales are sometimes spotted cruising through the area and orcas can make appearances on snorkel tours, leaving you breathless as you watch them hunt for rays. Even the enormous blue whale, the largest of all the whales, makes their rounds in these abundant waters. Mobs of mobula rays also make a quick appearance late November, early December so if you’re lucky, you could see them too!

Spring and Summer are for the sharks and rays

There’s nothing like being face to face with a shark, and Cabo San Lucas is bursting with a variety of our toothy friends. Bull sharks hang out in Cabo Pulmo, while hammerhead sharks cruise around Gordo Banks. White tip reef sharks are spotted at various sites in the bay and the corridor, while numerous pelagic sharks can be found off-shore like Makos, Blue, Silky, and even the elusive smooth hammerhead. Although sightings of specific shark species can never be guaranteed, this part of the coast is usually good for memorable shark dives throughout the year except when the water gets super warm in the early autumn. Cabo San Lucas plays host to thousands of Mobula rays that aggregate around the area in the late spring & early summer. There’s also a chance of spotting the famous Guitar ray in the springtime, if you’re lucky!

Fall is the warmest, clearest water

Not only is the water gorgeous, but it’s also booming with huge schools of sardines, snapper, jacks, puffers, goat fish, and even cow nose rays. The clear water offers up great photo opportunities for all the usual suspects which can be found year round in Los Cabos, including frog fish, sea horses, and rays. This is also a great time to head to Gordo Banks to look for hammerhead sharks.
