Whale watching in Mexico 2026-2027: season dates, where to go and tour prices

Q: Which whale you will see where

Humpback whale : the star of Los Cabos, Banderas Bay, Oaxaca and Guerrero. It comes to calve and mate; it is the one that breaches, slaps the water and sings. January and February bring the most activity. Gray whale : travels from Alaska to the lagoons of Baja California Sur (Ojo de Liebre, San Ignacio, Magdalena Bay) to give birth. In February and March mothers and calves approach the boats on their own: the closest encounter available anywhere in Mexico. Blue whale : the largest animal on Earth winters off Loreto, inside Bahía de Loreto National Park, between January and April. Seeing one takes luck and a good captain.

Mexico's 2026-2027 whale season starts, if Semarnat repeats the dates it sets every year, on December 8 in Banderas Bay (Puerto Vallarta and Riviera Nayarit) and December 15 in Los Cabos and the gray whale lagoons of Baja California Sur, running until late March on the central Pacific and until April 30 in Baja. A shared tour costs from about 999 MXN in Vallarta booked online, from 1,000 MXN with local operators in Cabo San Lucas, and 80 to 110 USD on the larger boats. Here are the dates by zone, which whale you will see where, real prices and the rules a serious operator must follow.

Official dates by zone

Every October Semarnat publishes the whale watching season by zone in the Official Gazette; the 2026-2027 notice is not out yet as of September 2026, but the dates barely change from year to year. These were the 2025-2026 dates, published October 2, 2025:

Banderas Bay (Puerto Vallarta, Nuevo Vallarta, Punta de Mita) and the rest of the Nayarit coast: December 8 to March 23.
Los Cabos and Cabo Pulmo National Park: December 15 to April 30.
Laguna Ojo de Liebre (Guerrero Negro) and Laguna San Ignacio: December 15 to April 30.
Magdalena Bay, La Paz and Loreto: January 1 to April 30.
Oaxaca (Huatulco, Puerto Escondido, Puerto Ángel): December 15 to March 21 or 31 depending on the departure point.
Guerrero (Ixtapa-Zihuatanejo, Acapulco): December 15 to March 20.

Outside those windows there are no observation permits, whales or not: an operator offering to go out earlier is breaking the law.

Los Cabos: prices, times and the best month

In Cabo San Lucas tours leave from the marina and last about two hours; the viewing areas are the tip of the Arch, the corridor toward San José del Cabo and the coast off San José. Prices published in February 2026 run from 80 to 110 USD per person on a shared boat, 90 to 130 USD on a small-group zodiac, and from 350 USD for a private boat; local operators advertise departures from 1,000 MXN with an open bar of domestic drinks. January and February have sighting success above 90 percent; the best slots are 8:00 to 11:00 and 16:00 to 18:00, with calmer seas and better light. Our Los Cabos guide covers the rest: where to stay, getting around and airport transfer costs.

Puerto Vallarta and Banderas Bay: the easiest bay

The bay is enclosed and deep, so humpbacks appear minutes from the pier. From the Puerto Vallarta maritime terminal there are three departures a day in season: 8:00 (back at 12:00), 9:00 (back at 13:00) and 13:00 (back at 16:00). An operator with a biologist on board charges 1,537 MXN per adult at the counter and 999 MXN booked online, with breakfast and open bar on the morning trips; children 6 to 11 pay 769 MXN at the counter or 499 MXN online. The pier fee and the whale conservation fee, about 33 and 25 pesos per person, are paid separately.

Two restrictions worth knowing: a 1.5 km radius around the Marietas Islands is closed to observation boats, and a 2 km coastal strip between Punta de Mita and the mouth of the Ameca River is off limits to protect mothers with calves. A good captain respects them without being asked. To get there, see the Mexico City to Puerto Vallarta route and the destination guide.

Guerrero Negro and San Ignacio: the gray whale that comes to the boat

The lagoons of the Vizcaíno desert are a different experience. Pangas of about eight meters leave the community pier at Ojo de Liebre with federal permits and spend about two hours on the water; Guerrero Negro hotels sell the package with transfer for around 45 USD per person (about 800 MXN) according to rates published for previous seasons, and at San Ignacio the lagoon camps combine boat, meals and a night in a cabin. From mid-February through March mothers nudge their calves toward the boats; the rule is to let them be the ones who approach.

Logistics are the hard part: Guerrero Negro has no regular commercial flights, so you drive or bus in from Tijuana or La Paz in a full day, or about five hours from Loreto. If you are doing the Tijuana to Los Cabos road trip, the lagoons are on the way and deserve two nights.

The NOM-131 rules and how to spot a serious operator

Standard NOM-131-SEMARNAT-2010 regulates whale watching across Mexico and is enforced by Profepa. The essentials:

Only boats authorized by Semarnat may operate, identified with the official flag for the season. Ask to see it before paying.
A maximum of four boats around any whale or group; the rest wait 240 meters away.
Speed under 5 knots (9 km/h) near whales and 2 knots (4 km/h) inside the observation zone, with no sudden acceleration or braking.
No swimming, diving or touching whales, no chasing, cutting them off or separating a mother from her calf.

If the captain speeds up to chase a breach, squeezes between a mother and calf or more than four boats crowd one animal, you are on the wrong tour. Operators that carry a biologist and cap group size tend to be the ones that follow the rules.

Getting there and where to stay

Los Cabos: flights to San José del Cabo airport (SJD) from most of Mexico and many US cities; stay in Cabo San Lucas to walk to the marina, or in San José for a quieter base.
Puerto Vallarta: PVR airport is 15 minutes from the maritime terminal; hotels in the northern hotel zone and Nuevo Vallarta are a short hop from the pier.
La Paz and Loreto: LAP and LTO airports have direct flights from Mexico City, Guadalajara and Tijuana; in Loreto boats leave from the waterfront.
Huatulco: flights to HUX; boats leave from Santa Cruz and the season lines up with the driest weather. See the Huatulco guide.

Compare flights to Los Cabos, Puerto Vallarta and La Paz two months out: January and February are high season in all three.

Which zone suits you

Tight budget: Puerto Vallarta. Tours from 999 MXN, departures minutes from the pier and hotels at every price.
Traveling with kids: Banderas Bay or Los Cabos on a large boat with a bathroom and shade; skip open pangas longer than two hours.
Photography: Los Cabos in January, with the Arch as backdrop and frequent breaches.
The closest encounter: Ojo de Liebre or San Ignacio in February or March, even at the cost of a day on the road.
Beach plus whales without a long flight: Huatulco from central and southern Mexico.

Practical tips

Take motion sickness tablets an hour before sailing, even if you have never been seasick: small boats move a lot in open water.
Bring sunscreen, a hat with a strap, a windbreaker and a waterproof pouch for your phone.
Choose morning departures: flatter sea, better light and more activity.
Ask about the boat's maximum capacity; above 15 people it is hard to see from every side.
Book online in advance for January and February: the web discounts are real and weekends fill up.
Leave the drone at the hotel: flying over whales is prohibited and licensed boats do not allow it.

Frequently asked questions

When does the 2026-2027 whale season start?

If last season's official dates repeat, December 8 in Banderas Bay and Nayarit, December 15 in Los Cabos, Ojo de Liebre and Oaxaca, and January 1 in Magdalena Bay, La Paz and Loreto. Semarnat publishes the final notice in October.

What is the best month for whale watching in Mexico?

January and February for humpbacks in Los Cabos and Vallarta; February and March for gray whales in the Baja California Sur lagoons, once the calves are born and approach the boats.

How much does a whale watching tour cost?

From 999 MXN per adult in Puerto Vallarta booked online, from 1,000 MXN with local operators in Cabo San Lucas, and 80 to 130 USD on shared boats or zodiacs in Los Cabos. A private boat starts at 350 USD.

Can you swim with whales in Mexico?

No. NOM-131 prohibits it nationwide; only observation from authorized boats at the distances set by the standard is allowed.

How do I know an operator is licensed?

It must display the official Semarnat flag for the current season and its authorization. No flag, no permit, however cheap the trip.

Is Guerrero Negro worth the trip?

If you want a gray whale and her calf a meter from the boat, yes. It is a full day on the road from Tijuana or La Paz, but no other zone offers that contact.
