The Humpback Whale is not in California. It is in the Pacific Ocean near California. The Humpback Whales migrate every year up and down the coast of California, down to Hawaii. There are also Humpback Whales in the Atlantic Ocean and in the Pacific Ocean surrounding the NW, W, SW, S, and SE coasts. It all depends on the time of year as to where the Humpback Whales will be as well as where they have grown up and lived their whole life.
