Swimming with whale sharks is an experience of a lifetime, and Cancun, Mexico, is one of the finest places to witness the largest fish in the world in their natural habitat.
Not only are these giants of the sea huge (the biggest one ever measured was an incredible 18.8 meters (61.7 feet) long), but they’re also graceful and entirely peaceful. Although they may be massive, you can be assured that whale sharks are only interested in eating tiny plankton, not the visiting tourists!
Swimming with whale sharks in Cancun is possible thanks to them appearing reasonably predictably in the nearby Caribbean Sea. Every year, between June and September, whale sharks gather in large numbers to feed in the warm waters off the Yucatán Peninsula.
Numerous tour operators arrange boat trips from Cancun to swim and snorkel alongside the whale sharks. But to have an unforgettable AND responsible time, all visitors must understand that whale sharks are an endangered species, and human behavior can easily harm the animals we want to see.
We will show you the importance of ethical whale shark tourism and provide tips on choosing a reputable tour provider who cares about the sharks and follows the rules. It’s vital to avoid operators who don’t act in the animal’s best interest and just want your money.
Swimming with whale sharks is not just an adventure but also a unique opportunity to learn about these magnificent creatures and their importance to the marine ecosystem.
By choosing to swim with whale sharks ethically, you can contribute to their conservation and encourage eco-tourism.

Where Can You Swim With Whale Sharks in Cancun?
Whale sharks like warm, open seawater where there’s plenty of plankton (tiny ocean organisms) for them to eat.

Thankfully, during the summer, this perfectly describes the Caribbean Sea off Cancun, Mexico. Whale sharks migrate here predictably each year in big numbers allowing you to swim with them in the wild.
One of the main areas where whale sharks are seen is the tropical waters reasonably close to the Cancun coast. In addition, they are also reliably found around the islands Isla Mujeres, Isla Contoy, and Isla Holbox off the Yucatan Peninsula, to the north of the main resort.
All these locations will require a boat trip as the sharks generally prefer to stay in deeper water away from the beaches.
When Is the Best Time To Swim With Whale Sharks in Cancun?
The best time to swim with whale sharks in Cancun is in July and August when the sharks are around in the highest numbers and sightings are the most reliable.

However, if you can’t visit during those months, the “Cancun whale shark season” typically runs between mid-May and mid-September. That said, this can change slightly every year.
So, if you’re planning a trip towards the beginning or end of the expected season, it would be a good idea to contact operators beforehand to check the current conditions.
Did You Know: Sharks mostly like warm water, but there are also cold water sharks.
How Can I Get To Cancun To Swim With Whale Sharks?
Flights from Europe, North America, and the rest of the world arrive daily at Cancún International Airport, and from there, it’s approximately a 20-minute trip by car to the Hotel Zone.
If you’re already in the country, you could take an internal flight or use one of the bus companies that operate routes to Cancun from the major cities in Mexico.
Once you’ve arrived, if you didn’t book a trip in advance, you can speak to your hotel or visit the marina to arrange a tour to swim with the whale sharks.
What Should I Expect From a Whale Shark Swimming Trip?
How Long Does a Typical Whale Shark Swim Last? – Expect about seven to ten hours. Depending on the schedule you’ve booked, you may be back at the marina at about 2 pm.
Alternatively, you could have a longer day out, including lunch on the beach at Isla Mujeres with coral reef snorkeling on the way back to Cancun.

Almost all excursions start with collection from your hotel or meeting at the marina between 6 and 8 am. Don’t be late!
The boat trip takes 30 minutes to an hour or more, depending on the destination. Although the seas are generally pretty calm, it’s worth taking sea sickness medication in advance if you know you’re likely to suffer.
The guides should use the opportunity during the boat ride to give you all the information you need to swim with the whale sharks. Pay close attention to get the most from the trip, and stay safe.
Whale sharks are large, dark with spots, and spend almost all their time close to the surface.
That said, it could take a little time for the crew to locate one to swim with, so you might need to be patient and wait, ready with your mask and wearing your snorkel life vest.
When it’s ready to swim, you’ll enter the water as instructed without splashing. It’s easy to get distracted by seeing such incredible creatures for the time, but make sure you pay attention to the guide.
It’s normal to take two people into the water at a time to swim with the sharks.
Whale sharks move constantly, and you’ll swim alongside them while the boat follows at a suitable distance. Make sure you follow the “no touching” rule.
Your guide will swap people on and off the boat so everyone gets a turn. Typically you’ll get two or three turns each for several minutes or more.
After you’ve enjoyed swimming with the sharks, you might have lunch as the boat returns to Cancun or head to one of the islands.

Is Swimming With Whale Sharks Safe?
Yes, swimming with whale sharks is safe if it’s done responsibly with a reputable tour operator. The activity is highly regulated in Mexico, and strict rules exist to ensure the safety and well-being of sharks and visitors.
