The optimal period for observing humpback whales in Hawaiian waters is generally mid-November through early May. These months encompass the majority of the whales’ annual migration from their feeding grounds in Alaska to the warmer, shallower waters surrounding the Hawaiian Islands for breeding, calving, and nursing.
Understanding this seasonal migration pattern is essential for planning a successful whale watching excursion. The concentration of whales peaks between January and March, offering increased opportunities for sightings. Historically, whale watching has contributed significantly to the Hawaiian tourism industry and fostered awareness regarding marine mammal conservation.
