Whale watching guide
You can search for whales by land or sea pretty much at any time of the year in San Diego. Year-round, it’s possible to spot Humpback, Minke and Finback whales. Gray whales migrate mid-December to April and blue whales migrate mid-June to September. While gray whales are easy to spot offshore from places like the Torrey Pines State Natural Reserve, blue whales tend to migrate in deeper waters and are best spotted from a boat. Book a San Diego whale watching tour at Next Level Sailing and you may run into sea lions, seals and dolphins, too. Kids and adults will love this exhilarating experience.
Search for sea life in local tide pools
Low tide means San Diego tide pools are plentiful, and looking for organisms like sea cucumbers, sea anemones and starfish is fun (and free!) for the whole family. Low tide at sunset is magical and romantic too.
Seals and sea lions
Seals and sea lions are some of San Diego’s most prolific animals. You’ll find them lounging on beaches, docks, and buoys along the coast. They lounge in the sun to get warm before they slide back into the water to hunt.
Green Sea Turtle
One of the best San Diego wildlife species is the Green Sea turtle. San Diego wildlife Green Sea Turtles love the warm, shallow waters of the San Diego Bay. They like to hang out in the eelgrass, where they munch on seaweed. Green sea turtles migrate to nesting grounds off the coast of Mexico. La Jolla Ecological Reserve is a good place to see the turtles in late summer and early fall. You can snorkel or kayak out to get a better look.
We can see why San Diego prides itself as America’s Finest City. With more than 100 miles of coastline and world-class attractions, you won’t be wondering what to do, but how to fit it all in! There is absolutely no better way to see marine life in San Diego than on a private boat cruise San Diego excursion available at Next Level Sailing.
