Puerto Vallarta is currently witnessing an extraordinary natural phenomenon, with humpback whale activity reaching levels rarely seen in modern history. According to the Whale Ecology and Conservation Association (Ecobac), the 2026 season has far exceeded scientific expectations. While researchers typically expect two sightings per hour, they are currently averaging five per hour, with some observers reporting as many as 100 whales scattered across the bay at once.
This surge is particularly unusual given this year’s warmer ocean temperatures. Typically, warm water sends whales further south, but an abundance of local marine life has kept them in Banderas Bay in record numbers. The northern part of the bay has become a bustling nursery for mothers and calves, as well as a high-energy stage for competing male groups. During a recent three-hour survey, technical teams documented 22 whales in a single concentrated zone—an astonishing density for the region.
With record numbers of whales and high vessel traffic, officials are urging extra caution. Sadly, three whale calves have already been struck by boats this season. The official season runs until March 23, 2026. With current numbers so high, researchers suggest this may be the best window for sightings in over a decade.
