Puerto Vallarta, México – Banderas Bay is experiencing an extraordinary winter as humpback whale populations reach levels rarely seen in modern history. According to recent data from the Whale Ecology and Conservation Association (Ecobac), the 2026 season has far surpassed initial scientific projections. While researchers typically expect to see about two whales per hour, current surveys are recording an average of five, with some lucky observers witnessing up to 100 whales across the bay at a single time.
This surge in activity is particularly fascinating because ocean temperatures have remained warmer than usual this year. Typically, such conditions encourage whales to travel further south in search of cooler water, but the abundance of marine life in the region has kept them here in record-breaking numbers. During standard three-hour monitoring trips, technical teams have documented as many as 22 whales in specific concentrated zones, highlighting the bay’s status as a premier destination for marine migration.
The northern reaches of the bay have become a vital sanctuary, serving as a bustling nursery for mothers with their calves and a stage for energetic competing groups. Because the density of these animals is so high, experts like Astrid Frisch Jordán are emphasizing the importance of maritime safety. With the increase in vessel traffic during the winter season, the risk of accidental collisions rises, making careful navigation more important than ever to protect these gentle giants.
As the official whale watching season continues until March 23, visitors are encouraged to participate in this natural spectacle through responsible tourism. To ensure a safe experience for both humans and wildlife, travelers should look for vessels flying the official whale-watching flag. These certified boats are marked with specific identification numbers and “JAL y Nayarit,” signifying that the crew is trained in conservation regulations and dedicated to minimizing disturbances to the animals.
By supporting these certified operators, guests contribute directly to the ongoing protection of the humpback population. While the wild nature of the ocean means sightings can never be fully guaranteed, the current record numbers make this year an ideal time to head out onto the water. Those who witness these massive creatures breaching or flipping their tails are treated to a powerful reminder of the beauty found within the local ecosystem.
