Each winter, North Pacific humpback whales migrate to Hawaiian waters. From the Waiʻanae coast, we get front-row seats to breaches and tail-slaps.

We follow NOAA's responsible-wildlife guidelines on every cruise — always 100 yards, always respectful.

What you'll see

Whales — and their neighbors — off Waiʻanae

Humpbacks are the winter headliners, but the leeward waters stay busy with dolphins that share the same coast.

Oʻahu whale watching

Humpback season on the Waiʻanae coast, December through May.

Every winter, North Pacific humpback whales travel thousands of miles to Hawaiʻi's warm, sheltered waters to mate, calve, and nurse their young. The season runs December through May, and Oʻahu's leeward Waiʻanae coast — protected from the trade winds and open-ocean swell — is one of the calmest and most reliable stretches of water on the island to watch them breach, tail-slap, and blow.

During whale season, Ocean Joy Cruises' Snorkel & Dolphin Watch cruises become Snorkel & Whale Watch cruises. Departing from Ko Olina Marina near Kapolei, ʻEwa Beach, and Makakilo, we sail into leeward waters where humpbacks gather, adjusting our route to the day's sightings and lingering as long as the whales do.

We watch whales the way federal law requires — from at least 100 yards away. We never chase or crowd them, so these visiting giants can rest and raise their calves undisturbed.

Whale watching FAQ

When is whale season in Oʻahu?
North Pacific humpback whales (koholā) migrate to Hawaiian waters each winter to mate and calve. The season runs December through April, and the calm leeward Waiʻanae coast is one of the most reliable places on the island to watch them breach and tail-slap.
Are whale sightings guaranteed?
Humpbacks are wild animals, so we can never guarantee a sighting — but during peak season they are seen very often from the leeward coast. We view them responsibly and never chase or crowd them.
Do we still snorkel on a whale-season cruise?
Yes. Our morning and afternoon cruises run about 3.5 hours and still include roughly an hour of guided snorkeling at a protected reef, plus a Hawaiian buffet and drinks — with whale watching added on during the December-through-April season.
