California gray whales pass Point Reyes on their seasonal migrations. On their southern migration, they pass Point Reyes in late December through early February. On their northern migration from Mexico to Artic feeding grounds, they pass Point Reyes in early March through early May. In the spring, whales stay close to shore, just beyond the breakers off the beaches or next to the rocky walls of the Point Reyes Headlands, while in winter they are usually farther offshore. Gray whales can be spotted by their spouts, air exhaled through their blowholes that rises 10-15 feet and condenses into a white vapor.
