Koholā (Humpback Whales) Like some species of birds that winter in the islands, humpback whales (koholā in Hawaiian) make long seasonal migrations to Hawaiʻi. Beginning in November, whales arrive in the Hawaiian Islands and will spend the winter calving and breeding in near-shore waters. They can grow to be 50 feet long (15 m) and weigh up to 40 tons (36,000 kg).
