Humpback Whales in Banderas Bay: A Historic 2025-2026 Season

Every winter, the majesty of humpback whales transforms the waters of Banderas Bay into an unparalleled natural stage. However, this current season has surpassed all expectations: their high presence has captured the attention of both specialists and travelers who are attuned to the beauty of the marine environment.

According to recent data from the Whale Ecology and Conservation Association (ECOBAC), the 2025-2026 season has far exceeded initial scientific projections. Under typical conditions, researchers expect to observe around two specimens per hour during their monitoring rounds. Today, censuses are recording an average of five, with estimates pointing to the simultaneous presence of up to 100 whales within the bay at certain times.

The contrast is even more remarkable when considering that ocean temperatures have remained warmer than usual. In theory, this scenario would favor the cetaceans continuing their movement toward cooler waters further south. However, the abundance of marine life in the region has created the perfect conditions for them to remain here in record numbers, reaffirming the biological richness that distinguishes this Mexican Pacific destination.

During standard three-hour monitoring trips, technical teams have documented up to 22 whales concentrated in specific areas, solidifying the bay as a privileged enclave within the migratory route. For those who venture out to sea, the spectacle is breathtaking: gravity-defying breaches, fin slaps echoing across the surface, and tails rising with elegance before a deep dive. Every movement is a monumental choreography that serves as a reminder of the scale and power of nature.

With the official close of the whale watching season set for March 23rd, this is a particularly opportune moment to live the experience. The invitation is clear: do so under the principles of responsible tourism and opt for vessels that carry the official whale watching flag (identified by specific numbers certifying their crew’s training). This ensures compliance with conservation regulations and minimizes any disturbance to the animals.

In the blue vastness of Banderas Bay, humpback whales are not just the stars of a significant scientific phenomenon, but also of a deeply emotional experience for those seeking an authentic encounter with the greatness of the ocean in Vallarta · Nayarit.
