When is whale season on Maui? A month-by-month guide

The season at a glance

Whale season begins in December. The first scouts show up in October and November, but it is in December that the ʻAuʻau Channel fills, the boats go out every day and the first calves are born. The season peaks from January through March and tapers through April; a few mothers with late calves hang on into May. The Hawaiian Islands Humpback Whale National Marine Sanctuary calls its official season December 15 to May 15.

Best month

February, if you can only pick one. It has had the highest numbers in the volunteer counts in almost every recent year, and it is when the whole island celebrates: Pacific Whale Foundation’s World Whale Day week (February 9 to 15 in 2026), the Great Whale Count and the Sanctuary Ocean Count all fall in February. In the February 2026 Great Whale Count volunteers tallied 847 whales off Maui in a single morning, the most of any island, and 1,935 statewide.

January is nearly as busy and has the freshest calves. March is the third peak month and the one many captains quietly prefer: calves are two months old and breaching for practice, competition pods are still forming, and the trade winds often settle.

Late March and April are the sleeper picks. Boats are less full, the water is calmer and warmer, and the whales that remain are mostly mothers with calves who stay close to shore and move slowly. You will see fewer animals overall but often have longer, closer encounters.

Early December is a gamble that usually pays off. There are fewer whales than in February, but there are also fewer people, and the ones that are here are often the big, active males.

Time of day

Morning. The ʻAuʻau Channel is sheltered from the trade winds by the West Maui Mountains, and until about 11 AM it is often glassy. Flat water means you can spot blows a mile away and see the whale’s whole body when it surfaces. By early afternoon the wind usually comes down the mountain and puts a chop on the surface that hides everything but breaches.

Morning light is also better for photographs and the whales are often more active after resting overnight. Both operators on this guide run their first trips early: Maui Whale Adventures goes out at 7:00 AM, Teralani’s Classic sails at 7:30 and 10:00 AM. Teralani’s Premium Whale Watch is the exception, sailing at 12:30 PM with lunch, which works because the catamaran is big enough to be comfortable in a little wind and has sails to steady it.

2026–27 season

The first whale of the 2025–26 season was reported off Maui on September 21, 2025, one of the earliest on record. Expect the first 2026–27 sightings in the last week of September or early October.

When to book

For a trip between January 10 and March 20, book at least a week ahead, and two or three weeks for the 7:00 AM raft or any weekend. Tours on Presidents’ Day week and spring break sell out. Outside peak you can usually book a day or two ahead, and both operators offer a free second trip if you somehow see no whales.

If you are watching the weather: a Kona (south) wind cancels more trips than rain. Rain in West Maui is usually brief and the whales do not care. A big north swell closes the Kāʻanapali beach landings for a morning or two a winter; operators will text you.

What a typical day looks like, by month

• Early December: three to eight whales in a two-hour trip, mostly adults, lots of travelling and blows, some breaching. First calves.
• Mid January: a dozen or more, competition pods of four to ten males chasing a female, singers audible on the hydrophone within minutes of dropping it.
• February: too many to count. The captain picks which pod to watch. Mothers and calves resting in the shallows off Olowalu and Launiupoko, pods fighting in the channel, breaches on the horizon in every direction.
• Late March: calves getting bold, mugging boats. Males starting to leave.
• April: mothers and calves, slow and close. Quiet boats. Warm water.
