Each year approximately 4,500 Hawaiian Humpbacks migrate from Alaska to breed, give birth, and bask in the warmer waters of Hawaii.
Kohola begin arriving in Hawaii in November, with the peak of migration and activity occurring in February and March. Scientists speculate that the whales use ocean currents, temperature changes, acoustical cues, and the Earth's magnetic field to find their way to Hawaii (the most remote island chain in the world).
Most whales remain in Hawaii for 6-8 weeks, with some extending their "vacation" to late May or early June. At the end of their time in Hawaii, the whales return to the food-rich waters of Alaska to feed and replenish their blubber in preparation for their next journey to Hawaii.
