The migration brings Humpback Whales back into the Sea of Cortez area beginning in the middle of November. Typically we see adult Humpback Whales transiting through the area from mid November until early December. By mid December the population of Humpback Whales is nearing its peak and the activity level overall is high. This continues until late January with adult Humpback Whales dominating. In late December and into January we start to see new born baby Humpback Whales. By early February the baby Humpback Whales start to become more active and their energy and activity level dominates until the end of the season in April.
The blue whale is the largest animal to ever live on this earth and can grow to over ninety feet in length. They are also the loudest, a screaming blue whale can be heard for several miles underwater. Blue whales can be found in the Sea of Cortez during the winter months when the water is cool.
Other whale species that frequent the Sea of Cortez include the Sperm Whale, Minke Whale, Fin Whale, and more.
