Our three-hour gray whale watching trips from Half Moon Bay are running every weekend through May 15. Sign up today!

The annual gray whale migration is one of the world's most magnificent and accessible wildlife spectacles. Each fall, thousands of gray whales migrate from their summer feeding grounds around Alaska down to the waters of Baja California, Mexico where they breed and calf. In the spring, the whales and their calves migrate back up north for the summer.

Their migration pathway follows closely along the California coast, providing us with outstanding opportunities for coastal whale watching.

Oceanic Society offers gray whale watching from December to May out of Half Moon Bay, California. Trips from Half Moon Bay last for 3-hours, with departures on Saturdays and Sundays.

What We See


The focus of our trip is to observe gray whales as they migrate from feeding grounds in Alaska to breeding areas in Mexico, then return back north again to Alaska. We often see gray whale mother and calf pairs (the calves having just been born in Mexico), as well as whales traveling individually or in small pods. We also regularly encounter California sea lions, harbor seals, and harbor porpoises, and occasionally see humpback whales, Dall's porpoises, elephant seals, Steller sea lions, and other species.


We see a wide range of seabirds on every trip. Some of the species we encounter are: Common Loons; Eared Grebes; Western Grebes; Brown Pelicans; Double-crested Cormorants; Brandt's Cormorants; Pelagic Cormorants; Black Scoters; Surf Scoters; White Winged Scoters; Black Oystercatchers; California Gulls; Herring Gulls; Western Gulls; Heerman's Gulls; Common Murres; Pigeon Guillemots; Buller's Shearwaters; Sooty Shearwaters; Red-necked Phalaropes; Cassin's Auklets; Rhinoceros Auklets; Northern Fulmars

For those who don't want to wait patiently for the action to come to them, catch a ride aboard a whale watching expedition out of Pillar Point Harbor in Half Moon Bay [...] Sightings are not guarantees ... but if it's rush hour, the payoff is great.

The Oceanic Society runs top-notch, naturalist-led, ocean-going weekend boat trips – sometimes to the Farallon Islands – during both whale-migration seasons.
Lonely Planet
On trips out of Pillar Point Harbor, I've seen whales parallel the boat's course for an hour. They can give a tail salute, spy-hop, even breach, with lots of "puff-of-smoke" spouts, as in, "There she blows."
