A blue whale with albinism surfaced in Bahía de Loreto National Park on March 6, making it the first documented albino blue whale in Mexican waters. CONANP, the federal agency that manages Mexico’s protected natural areas, confirmed the sighting and called it an unprecedented moment in the country’s cetacean records.
Scientists estimate that albinism occurs in roughly 1 in 40,000 blue whales. Caused by a hereditary absence of melanin, the condition appears in 21 cetacean species worldwide, but researchers have confirmed very few cases in blue whales. The most famous white whale, a humpback named Migaloo spotted off Australia in 1991, remains a subject of debate among researchers who suspect leucism rather than truly albino.
An Exceptional Season in Loreto
The albino blue whale sighting in Loreto caps what marine biologists are calling one of the best blue whale seasons on record in the Sea of Cortez. Whales arrived as early as January 11, weeks ahead of the typical early-February start. After just two weeks of observation, researchers had already identified more individual blue whales than they normally catalog in an entire average season. As of March 7, at least 30 distinct specimens had been confirmed within the park.
Multiple tour operators reported rare surface feeding behavior, with videos of whales lunging through krill swarms near the islands of Carmen, Danzante, and Monserrat circulating widely on social media. Blue whales typically feed at depth, so the surface activity suggests unusually dense concentrations of food in the park’s waters this year.
Baja California Sur also has a history with white cetaceans. A gray whale with albinism nicknamed “Galón de Leche” first appeared as a calf during the 2008-2009 season and gave birth to her own calf in 2017. Only three or four albino gray whales have ever been recorded worldwide.
Where to See Blue Whales in Loreto
Blue whale season in Loreto runs from January through March, with peak sightings in February. Several licensed operators run daily excursions from the Loreto Marina and Marina Puerto Escondido. Standard tours cost 2,200 to 3,500 pesos ($125 to $200 USD) per person. Most run from 8 a.m. to early afternoon and include lunch, marine park permits, and a safety orientation.
The park itself covers 2,065 square kilometers of the Sea of Cortez, with 88 percent ocean surface and five main islands: Coronados, Carmen, Danzante, Monserrat, and Santa Catalina. Beyond blue whales, visitors this season have spotted fin whales, humpback whales, orcas, and dolphins.
Loreto is a two-hour flight from Tijuana or a scenic but long 10-hour drive down Highway 1 through the Baja peninsula. The town featured in our recent guide to the best tacos in small-town Baja California Sur, where the whale-watching capital doubles as home to some of the region’s best seafood.
The Bigger Picture for Baja Whale Watching
The blue whale activity in Loreto is part of a banner year across the entire peninsula. On the Pacific side, gray whales packed the lagoons of San Ignacio and Guerrero Negro through their December-to-April season, with the “friendly whale” encounters that draw tourists from around the world to pet wild cetaceans from small pangas. Humpback whales have maintained a constant presence off the Los Cabos coast since December.
Bahía de Loreto National Park holds RAMSAR designation as a wetland of international importance and supports higher marine mammal diversity than any other site in Mexico. The IUCN lists the blue whale as endangered, making every documented individual scientifically valuable, and an albino specimen doubly so.
With whales still actively feeding in Loreto as of March 7, the season is running late. Anyone who missed the usual February peak still has time to book a boat.
