Swim with Whale sharks Playa del Carmen, Cancun, Holbox, and Isla Mujeres, Mexico We are getting more and more excited, the closer we get to the month of June when Isla Mujeres Whale shark season officially begins. Every year, when the sea temperatures rise, huge amounts of plankton come pouring out of the Gulf of Mexico and into the Caribbean.

In preparation for our favorite time of the year, we wanted to share with you everything you need to know about swimming with whale sharks in Mexico.

These animals know that and migrate every year to these nutritious areas in the north of the Yucatan peninsula of Mexico.

When does the whale shark season start in the Riviera Maya?

Observing and swimming with whale sharks takes place in a protected area, due to the importance of its eco-system and the flora and fauna it contains. To protect the area the ministry of environment and human resources established a set of rules (Plan de manejo) also known as the “Biosphere Reserve Management Program”.

Which governs when the Whale Shark tours in The Rivera Maya can begin and must end. Their authority covers the area in the marine zone northeast of the Yucatan Peninsula, including the Biosphere Reserve Tiburon Ballena (Whale Shark) and to the Yum Balam Flora and Fauna Protection Area and the northern region of the Mexican Caribbean Biosphere Reserve.

The whale sharks are non-mammalian vertebrates, originated about 60 million years ago and can be found in open waters of the tropical oceans. Whale Shark Reproduction Whale sharks are ovoviviparous and females give birth to live young that are about two feet long. Their age at sexual maturity and length of gestation are unknown, but it is believed to be in the range of 25-30 years. Not much is known about breeding or birthing grounds either.

In March 2009, rescuers found a 15-inch long baby whale shark in a coastal area in the Philippines, where it had been caught in a rope. This may mean that the Philippines is a birthing ground for the species. Whale sharks appear to be a long-lived animal. Estimates for the longevity of whale sharks are in the range of 60-150 years. They do not have any natural predators but are threatened by humans because they hunt for their fins.

You might be thinking, what is this all about? Swimming with whale sharks in the middle of the ocean! While whale sharks have a huge mouth, they almost exclusively feed from plankton. That is why they are absolutely harmless to humans. They are mainly interested in fish eggs, algae and krill, and they are definitely not interested in the person swimming next to them.
“Gentle giants” The eco-touristic activity of swimming with whale sharks in the surroundings of Cancun, the Island of Holbox and Isla Mujeres started around twelve years ago.

The fishermen would call a whale shark “Domino,” because of its characteristic white dotted pattern. Today, we know the big fish to be “gentle giants” and that is what we call them these days.

Swimming with Whale Sharks 2019 [updated]Once you are on board we will introduce you to the crew. All the boats have a maximum capacity of ten guests. While leaving the port, your guide will give you a detailed briefing about the “do`s and the don’ts” and the mate will hand you your equipment.

In the best-case scenario the boat ride takes around half an hour and in the worst case up to three hours. We don’t want to scare you, we want to be honest. Looking for whale sharks in the middle of the ocean is similar to searching the needle in the haystack.

Sea Sickness If you are prone to motion sickness we advise you to take Dramamine the day before!​ Many times people get motion sickness once we find the whale sharks and the boat stops. There are many different things you can do to deter motion sickness.

In general, it is wise to take it easy the day before. Since you will be getting up early and doing physical exercise the following guidelines are recommended: Tips to avoid motion sickness:

  • Stay hydrated, eat some light food for dinner and breakfast.
  • If you get motion sickness easily it is recommended to take Dramamine the day before, so your body is getting used to it.
  • The University of Maryland Medical Center recommends trying ginger tea or taking a 250-milligram capsule three times a day.
  • Try bracelets against motion sickness.
  • Learn more about pressure points to relieve motion sickness.
  • Do not drink (excessively) alcoholic or caffeinated drinks the day before and get a good 8-hour rest.

“Look for a grey patch in the size of a school bus!”

We recommend you to get familiar with the equipment during the ride. Put the mask on and adjust it, so it is not too loose or too tight. See if the snorkel is located properly and fits easily in your mouth. Try the fins on and let the crew know if you need a different size. It is important to be ready when arriving at the whale shark area. We are actually in a National Park and that is why certain rules apply, like wearing the lifejacket. Once we are about to arrive at the area of the whale sharks the crew will give you a heads-up. This is your sign to gear up and get ready.

Remember the crew is always here to help you! The ten guests will be divided into five teams of two with the first team getting ready in the back of the boat, while the captain is looking for a whale shark. The mate and the first two guests are sitting on the edge of the boat with their fins outside facing the water, waiting for the signal of the captain.

Once the boat is in the right position the mate or the captain will give you the signal to get into the water. In the water stay with your guide, and he will lead you toward your whale shark, which you will be snorkeling next to. Your guide will be next to you the entire time, taking care of you. Whale sharks swim an average of 7 km/h or 4 mph.

This is enough to eventually outpace you, so once you see the huge tail it is time to get back to the boat, giving the next team the chance to get into the water and wait for your next turn. In that way, you can rest and everybody gets the chance to see the whale sharks. Make sure you have some water on hand and stay hydrated. Exhausted and happy… …that’s how you will leave the Whale sharks behind.
