Humpback whales grace Hawaii's waters from November to April, with the prime viewing season from January to March. They migrate from Alaska to mate and give birth, showcasing behaviours like attracting mates, teaching newborns to swim, and leisurely cruising along the coast. This private cruise aboard a 30-foot power catamaran called Keanuenue not only offers an exclusive encounter with these majestic creatures, but also provides stunning views of the iconic south side of Oahu.
