Just how close are these gentle giants getting to the shore?
According to Craig Stanton, of Voyager Excursions, a whale-watching tour company, the whales have been within one to two miles of land.
"We get a few stragglers that get within a few hundred yards of the mouth of the harbor," Stanton said. "It's to the point where we get paddle boarders and kayakers getting alongside of them, which is pretty unique."
CBS News correspondent Hattie Kauffman points out that this is a scene that couldn't have happened just a few years ago. Blue whales were hunted almost to extinction. They are still considered endangered, with only 8,000 to 9,000 in all the oceans of the world.
In the exact same spot at the exact same time in 2010, nearly 200 whales surfaced along the Southern California coastline in search of their favorite food, a tiny shrimp called krill. Experts believe colder water temperatures are creating a perfect harbor for krill and, as a result, these gentle giants.
