Whale shark season in La Paz: when it is and how to book

The whale shark is one of the most sought-after experiences in La Paz and one of the few places in the world where you can swim alongside the largest fish on the planet in a controlled setting. Unlike other destinations, the sharks here come close to the surface in the bay to feed on plankton, making it possible to observe them without deep diving. This guide summarizes the real season we operate from our base on the malecón.

When is whale shark season in La Paz?

The official whale shark watching and swimming season in La Paz generally runs from October to April. The months with the highest concentration of sharks are November, December, January, February and March. Sightings depend on food availability and ocean conditions, so there is never a guarantee, but local operators know the spots and times with the best probability.

The low or closed season is usually from May to September, when whale sharks migrate to open Pacific waters and regular departures are not offered.

Where does the whale shark tour take place?

Whale shark tours depart from the La Paz malecón and head into the bay, mainly around El Mogote and nearby areas where plankton-rich waters concentrate. The boat ride lasts between 20 and 45 minutes depending on where the sharks are located that day.

Sightings happen in open water, but usually in relatively calm seas. Each boat has a certified guide who locates the sharks and coordinates swim turns so the animals are not crowded.

Official rules for swimming with whale sharks

Whale sharks are protected by Mexican environmental regulations. It is not a free activity: only authorized boats and guides may operate. These are the rules that apply on all our tours:

• Guided swim mandatory: always accompanied by a certified guide.
• Minimum distance: do not touch, ride or chase the animal.
• Small groups: maximum two swimmers per whale shark at a time.
• Biodegradable sunscreen: mandatory before entering the water.
• No flash or drones: devices that disturb the animal are not allowed.
• Follow the guide's instructions: if the shark moves away, do not pursue it.

How long does the tour last and what is included?

A whale shark tour in La Paz lasts approximately 2 to 3 hours in total, although the actual swim time with the animal is usually just a few minutes per person. The itinerary includes:

• Boat transfer from the La Paz malecón.
• Snorkel gear: fins, mask and snorkel (life jacket available).

• Apply biodegradable sunscreen before leaving and avoid perfume.
• Bring a dry towel and a change of clothes for the return.
