When Is Whale Season in Hawaii?

Humpback whale season in Hawaii generally runs from November through May, with the most dependable viewing from January through March. A few early whales can appear in late October, sightings build through November and December, and the peak winter months bring the highest activity around Maui, the Kohala Coast, Kauai, and Oahu's leeward and southeast shores.

Humpback Whales in Hawaii

Why Hawaii?

North Pacific humpback whales migrate roughly 3,000 miles from Alaska to Hawaii each winter. They come to breed, give birth, and nurse calves in warm, shallow waters around the islands before returning north to feed.

What You'll See

Breaching (full-body jumps), tail slaps, pectoral fin slaps, spy-hopping (heads poking out), and spouts (exhale plumes visible from a mile away). Males sing repeated underwater song sequences that can continue for long sessions. Calves are especially playful and curious.

Best Time of Day

Early morning (7-10 AM) offers calm seas and active whales. Late afternoon is second-best. Midday tends to be rougher and glare makes spotting harder. Morning boat tours have the best conditions overall.

Federal Protection

Humpback whales are protected under the Marine Mammal Protection Act. In Hawaii, federal law prohibits approaching within 100 yards by boat, kayak, drone, swimming, or any other vessel or means. If a whale approaches on its own, give it room and follow the captain's instructions.
