What kind of whales are common in Hawaii?

In Hawaii, the most common whales are the humpback whales, which migrate to the warm waters of the islands from late November to early May for breeding and calving. Other species occasionally spotted include the gray whale and the sperm whale, but humpbacks are by far the most prevalent during the migration season. The islands also provide opportunities to see orcas and pilot whales, although these sightings are less frequent.
