Wow Your Kids With Easy Pacific Gray Whale Migration Trivia
Discuss the Pacific gray whale migration with any mother and I almost guarantee she’s thinking what I’m thinking–swimming 10,000 miles round-trip to give birth sounds like a pain. Nonetheless, San Diego residents are sighting whales right now from shore or by boat which means your kids may have whale-related “why” questions on repetition.
Sound like a genius by arming yourself with these fun facts as you keep an eye out for whales. Or, just show the kids this helpful map, courtesy of Birch Aquarium at Scripps, that illustrates the route in an easy-to-understand manner.
Easy Gray Whale Facts You Can Remember

Gray Whale Migration: Just The Basics
Gray whales eat bottom-feeding invertebrates in the arctic. They, basically, turn on their sides and scoop up sediment from the ocean floor. In the fall, as the arctic ice pushes south, the whales start to head south, too. During the journey, they feed opportunistically and by tapping into fat reserves. They pass by the western coast of Canada, Washington, Oregon, and California on their way to the warmer waters of Baja California, Mexico where they breed and give birth. The whales travel day and night at speeds of about 5 mph, as mentioned above.
The first whales to arrive are pregnant mothers and females ready to mate. It’s thought that the shallow lagoon waters also protect the whales from predators, such as sharks. Whales start to leave the lagoons in February. The last whales to leave are new mothers with their calves, who linger as long as possible (with some leaving in April and even May) in the warm water while waiting for the calves to grow strong enough for the journey. By mid March, most of the whales are seen off the coast of Washington.
However, we do have a few hundred rogue whales who hang out between California and Canada during the summer months. They’re called the Pacific Coast feeding group. For whatever reason, they don’t feel like heading all the way to the arctic. I can hardly blame them.

Should you choose to spot whales from shore in San Diego, it’s better to go now. January the month with the best odds. As they migrate north again, they usually swim too far out from shore to be seen.
