Enjoy the Unexpected in Jaltemba Bay: Crocs in the Ocean

Tara A. Spears

Sea lion, sea weed, crocs, oh my! 2026 is quite the year for unique and unexpected animal interactions in Guayabitos, Mexico. It seems that not only do the tourists love the beaches of Jaltemba Bay but the exotic wildlife does, too. You can blame it on the loss of natural habitat due to development; or blame the effects of climate change to alter the tides, water level, and rain patterns; or the explosion of human inhabitants in what was previously wild jungle; and the species adapting to the presence of cities and people. All of these changes help explain why the increase in crocodile sightings on Mexican beaches in the last month. It’s an environmental alert rather than an isolated coincidence.

Western Mexico, from Puerto Vallarta to Mazatlán, have witnessed an unusual and alarming phenomenon: the increase in crocodile sightings near the ocean. Tourists and locals alike are surprised, even frightened, by the presence of these reptiles, especially considering that there are no native saltwater crocodiles in Mexico.

Not salt water critters: Mexico is home to the Crocodylus acutus, commonly known as the American crocodile. Although this species primarily inhabits freshwater environments such as rivers, lagoons, and mangroves, it is capable of tolerating brackish water and sometimes even ventures into the sea. The recent exceptional rainfall during storms creates swollen rivers and estuary overflows that propel crocodiles into the ocean.

In some Mexican states like Jalisco, Nayarit, and Sinaloa, authorities have established protocols to capture and relocate crocodiles that approach tourist areas. They also place warning signs to inform visitors of potential risks. Although sightings are increasing, biologists clarify that crocodiles do not naturally attack humans unless they feel threatened or cornered. However, it is vital to maintain a safe distance and report any crocodile presence to local authorities.

Crocodiles tend to stay in one area—except during mating season. During this time, they search for suitable partners, and males become territorial as they compete for females. Actually, all crocs establish territory so be alert when hiking or hanging around streams. The crocs generally do not go looking for confrontations. They lead a solitary life and prefer to be alone, retreating from trouble. However, if they feel threatened by another animal (including a human), they will attack. On rare occasions, they have attacked and even killed humans.

In Nayarit, the rut season is May-June, which explains why there have been so many crocodile sightings earlier this summer. It’s important to be extra vigilant if walking through or near a mangrove/estuary where crocodiles live. Crocodiles bellow to convey health and size information to surrounding crocs for breeding, social, and territorial reasons — which gives the hiker a chance to avoid the wild animal. Crocs bellow year-round but with much more frequency in the breeding season.

At this time of the year, the rains cause the local waterways to expand, which encourages the crocs to explore. To add to the problem, urban expansion and tourism have encroached on the wetland habitats of these creatures, making encounters more likely. Sightings of crocs in local rivers and runoff canals have become more common. Surprisingly, there are resident crocodiles in the canal near Decameron in south Guayabitos, a high traffic tourist zone. Visitors post photos of the crocodiles all year round.

Vacationing in the tropics with its exotic animals and flowers is a unique and memorable experience. Just remember to keep a safe distance if you see a crocodile. If you see one in the ocean, contact the Bomberos immediately, 327 274 3578. While authorities are working to mitigate the risks, the responsibility of protecting nature also falls on each of us. Respecting wildlife and preserving ecosystems is the best way to ensure a balance between tourism and nature.
