Whale Migration in San Diego
Every year, thousands of Gray whales make their way down the Pacific coast to their breeding grounds in Baja California. And San Diego is one of the best places to catch a glimpse of these gentle giants in action. But the Gray whale isn’t the only one on the move – Blue whales and Humpback whales also make their way through our waters during their migration season.
How long is the Gray Whale migration?
The Gray Whale migration is an awe-inspiring journey that spans a significant distance. These magnificent creatures undertake a round-trip migration of approximately 10,000 to 12,000 miles (16,000 to 19,000 kilometers). They travel from their wintering grounds in Baja California, Mexico, to their feeding grounds in the Arctic regions, and then back again.
How many Gray Whales migrate to San Diego each year?
San Diego is fortunate to witness a significant number of Gray Whales passing by during their migration. Approximately 20,000 Gray Whales are estimated to migrate along the coast of California each year. While it is challenging to provide an exact count specific to San Diego, it serves as a popular destination for whale watching enthusiasts during the Gray Whale season.
Are Gray Whales dangerous to humans?
Gray Whales are generally known for their gentle nature and pose no significant threat to humans. They are known to be curious and may approach boats, providing incredible opportunities for up-close encounters. However, it is important to remember that they are wild animals, and it is advisable to maintain a safe distance and respect their natural behavior to ensure the well-being of both humans and the whales.
What do Gray Whales eat?
Gray Whales are filter feeders and primarily feed on small crustaceans known as amphipods and other tiny organisms found in the sediments of the ocean floor. They employ a feeding technique called “bottom feeding” where they stir up the sediment and filter out their prey using baleen plates, which act as a natural sieve.
How long do Gray Whales live?
Gray Whales have a relatively long lifespan compared to many other marine mammals. On average, they can live between 55 and 70 years. However, some individuals have been known to live beyond 80 years. The exact lifespan of a Gray Whale can vary depending on various factors such as environmental conditions, predation, and overall health.
What is the history of Gray Whale hunting in San Diego?
Gray Whales were once heavily hunted along the coast of California, including San Diego, during the whaling era. They were hunted for their valuable blubber, meat, and other products.

Today, Gray Whales are revered and celebrated as majestic creatures, and whale watching has become a popular activity in San Diego to appreciate their remarkable migration.

What do Humpback Whales eat?
Humpback Whales are baleen whales known as filter feeders. They primarily feed on small fish, such as herring and krill, as well as other small marine organisms. During feeding, they engulf large volumes of water and then use their baleen plates to filter out their prey, allowing them to consume vast quantities of food in a single gulp.
How long can Humpback Whales hold their breath?
Humpback Whales are remarkable divers and can hold their breath for extended periods. On average, they can stay submerged for around 10 to 15 minutes during a typical dive. However, they are also capable of diving deeper and holding their breath for up to 45 minutes in certain circumstances.
What is the lifespan of a Humpback Whale?
Humpback Whales have a relatively long lifespan compared to many other marine mammals. On average, they can live up to 45 to 50 years. However, there have been reports of individuals living beyond 80 years. The exact lifespan of a Humpback Whale can vary depending on various factors, including their environment, food availability, and overall health.
How do Humpback Whales communicate with each other?
Humpback Whales are known for their complex and diverse communication behaviors. They produce a wide range of vocalizations, including haunting songs and a variety of other sounds such as clicks, whistles, and social calls. These vocalizations play a crucial role in various aspects of their social interactions, mating rituals, and navigation. Humpback Whales also communicate through physical behaviors like breaching, tail slapping, and fin waving.
