Is it safe to swim in Puerto Vallarta?

There actually are crocodiles, jellyfish, and sharks in Puerto Vallarta. But is there any reason to worry? How is the ocean water quality?

Let’s go over the types of sharks that live in Banderas Bay, where river crocodiles can be found in the area, jellyfish season, red tide information, and other dangerous animals and wildlife.

Ocean Water Quality & Red Tide

Puerto Vallarta has the coveted Blue Flag status, an international certification that recognizes excellence in security, environmental management, and quality of beaches and marinas.

Also, the Mexican government agency, COFEPRIS, regularly does a sweeping ocean water quality test and bacterial analysis at all the popular beaches in Mexico. This program is called “Playas Limpias”.

According to the Ministry of Health, the ocean water quality must have less than 200 units of enterococci bacteria per 100 ml. That being said, the water quality tends to be lower near rivers mouths such as the Cuale or Ameca.

Red tide is a phenomenon that occurs mostly in the spring when algae grow out of control and it could ruin your beach visit, as your skin or eyes can become susceptible to some type of irritation.

August is the month with the highest ocean water temperature at 30°C.

Shark Attacks in Puerto Vallarta

There actually are sharks in Puerto Vallarta, but is there any reason to worry? The sharks in Puerto Vallarta that actually do still exist are either very small and harmless to humans or are plankton-eating.

So, why aren’t there any shark attacks in Puerto Vallarta?

Shark attacks in general are actually very rare in the world.

There’s a myth that dolphins patrol the area from any threats to the bay, but that seems unlikely. A more likely explanation is that sharks in Puerto Vallarta were over-exploited back in the 1930s and they simply have never recovered.

Sharks have low reproductive rates, and shark fin soup was very popular. Many types of sharks are still exploited for their fins as some consider them a delicacy, but the practice is cruel and unsustainable.

Back in 2008, there was news about a shark attacking 3 surfers in less than a month. This happened on the beaches close to Ixtapa-Zihuatanejo, about 10 hours south of Puerto Vallarta.

These attacks were associated with “La Niña” which modifies ocean currents and temperatures, and there have not been any other reported attacks in the last few years.

In conclusion, shark attacks in Puerto Vallarta are extremely rare, and the chances of you being the victim of one are so remote that it’s not something worth worrying about.

Are there crocodiles in Puerto Vallarta?

Only a few incidents have been reported over the years, but it does happen and it tends to get a lot of attention from the media.

During the rainy season, it is common to find these reptiles in the ocean due to the strong river currents that wash them into the bay. Their natural habitat is also being encroached upon and they have less space to live.

Because of this, they find their way into recreational spaces such as marinas and golf courses.

Their natural behavior is for them to come to the shore at night to rest.

Although they can be found in the bay, they tend to be concentrated in 2 different areas: El Salado State Park, a natural mangrove reserve near Marina Vallarta, and El Cora, a crocodile sanctuary.

El Estero is a protected area of mangroves and marshes. Its connection to the ocean is permanent, through a channel approximately 20 meters wide, 3 meters deep, and 2 kilometers long that ends at the port harbor.

There are almost 99 species of birds, 10 mammals, and 29 amphibians/reptiles. It is a great

The local American crocodile species is not as aggressive as the Floridan alligator, which has quite a reputation for attacking people.

A recent crocodile attack in Puerto Vallarta was in July 2021 when a river crocodile attacked an 18-year-old guest at the Marriott Puerto Vallarta, shortly before going on a nighttime swim.

Fortunately, she managed to escape and made a full recovery. Just for some perspective, the Marriot is relatively close to the Ameca River outlet and 2 km from a crocodile viewing area.

Crocodiles also normally hunt at night and prefer limited moonlight. If there is a high risk of crocodiles or if one was sighted, hotels will close the beach and set the flags to blue or black:

Jellyfish Season in Puerto Vallarta

Some beach destinations are home to extremely dangerous jellyfish, but fortunately, Puerto Vallarta is not one of those.

The ones that we do see are only around for a short amount of time, as they are simply passing through. They are seasonal visitors to the area, usually around the spring and summer months.

They are not very dangerous, but they may leave you with a painful sting.

The pain can vary from person to person and it depends on the jellyfish species, but we have heard of some rashes lasting for weeks. Other people that are stung are hardly bothered at all and consider it little more than an annoyance.

If you see a blob in the sand while you’re walking down the beach, avoid it and keep an eye out for any more after that. If you accidentally step on one, their sting can be very painful, even if they are already dead.

General Swimming Safety

Banderas Bay keeps Puerto Vallarta and its surrounding areas very safe from many things. The shape of the bay also protects the area from strong waves, making it great for swimming and water activities.

The best surf spots are mostly north, outside of Banderas Bay (like Sayulita) where it is the open ocean.
