The Best Time for Whale Watching in San Diego


San Diego offers a glistening coastline lively with animal activity year-round. Revel in the best whale watching experience from mid-December through April as gray whales migrate from feeding grounds in Alaska to Baja California and back. More than 20,000 gray whales complete this 10,000-mile round-trip journey every year. In Baja California, female grays give birth to their calves, spending time in the warm waters before heading north again in the early spring. With 70 miles of the San Diego coastline directly in the migration path, you can catch great views late in the season as females take their calves back north with them. According to the Birch Aquarium in San Diego, gray whales tend to travel alone or in pods of two or three and more of the mammals may be seen traveling together during peak migration season at about six mph. These majestic mammals won’t be hard to miss as they match about the width of a basketball court.

December through April, you are guaranteed a memorable and successful experience while whale watching within San Diego’s thriving marine world. During this time of year, a 4 hour cruise aboard the Yacht America will ensure marvelous whale and other aquatic life sightings worth a lifetime. Some other mammals viewed in the area include minke Whales, humpback whales, fin whales, orcas, Risso’s dolphin, bottlenose dolphin, common dolphin, and Pacific white sided dolphin.

Excellent whale sightings continue through the summer months during the blue whale migration. Known to be the largest creatures on Earth and the most endangered among great whales, blue whales are most likely to be spotted mid-June through September. Over the past few years, variations in ocean temperatures and copious amounts of krill have attracted even more blue whales to San Diego’s coast. These mammals like deep water, which is easily accessible from San Diego. The depth drops from 400 ft to 4,000 ft just a few miles offshore. During the summer months, about 2,000 to 3,000 whales feed off the California coast having traveled from Antartica, to California to eventually Costa Rica. Besides these gentle giants, other marine life present in the San Diego waters at this time of year include humpback whales, fin whales, pilot whales and killer whales.   

During whale watching season in San Diego, there are endless ways to see the annual migration without having to go far at all. Whales and other species are easiest to see from shore between mid-February through April during the gray whale northbound migration with the animals swimming closer to the shore to protect their newborn. Other times of the year, the whales are rarely visible from the shoreline even with binoculars in hand. 

To get a better understanding of what to expect while out on the water with Next Level Sailing, check out our more granular monthly whale sighting report below: 

January: Gray whale migration facts: January in San Diego is one of the best times to spot gray whales as they are typically mid-migration from Alaska to Baja, California. In addition, it’s normal to also spot humpback whales and dolphins.

March: Gray whales are still the predominant whale to be spotted during this time. Facts about gray whales is, other than their blow horns, another distinguishing factor is their dark gray bodies are covered in white patches, which are scars left from parasites. They also can carry up to 400 lbs of barnacles. 

April: Although the gray whale migration typically teeters off at the end of March, a few gray whales can still be spotted – sometimes even with their babies! Where do gray whales give birth? In three locations: Guerrero Negro, Ojo de Liebre and Laguna San Ignacio, which are all located in Baja! These lagoons are sheltered by strong winds and are typically more shallow, which is perfect for gray whales to give birth.

July: In addition to blue whales, you can also spot fin whales and humpback whales in July! Fin whales can be distinguished by their size as they are the second largest species on Earth. Humpback whales are often set apart from others due to their long pectoral fins and knobby heads.

August: August is usually the last time you can spot the largest species on Earth, the blue whale! They only swim out in the deep sea, which Next Level Sailing specializes in, so you are in good hands!

September: September is known for seeing more fin whales and humpback whales. It’s possible to see a blue whale, but not likely.
