Every winter more than 10,000 North Pacific humpbacks swim 3,000 miles from Alaska to the warm, shallow water between Lahaina and Lānaʻi. This is the guide to when they come, why they come, what they are doing out there, and the best ways to see them from the shore or the water.
Photo: HIHWNMS / NOAAWhale season starts in December. The channel fills through the month, January through March is peak, April is the quiet tail, and the last mothers and calves leave in May.
The best single month is February, but if you want a quieter channel and warmer, calmer water, late March and April are underrated. Read the month-by-month guide →
A small raft that sits at eye level with the water, or a premium catamaran with lunch and an open bar. Both load from Kāʻanapali Beach, both guarantee sightings, and we have been on both.
A fast, shaded twin-engine adventure raft that loads straight off the sand at Kāʻanapali Beach. Twenty guests max, a certified naturalist and a hydrophone on every trip, and you sit a few feet above the water. The closest you can legally get to a whale.
Teralani's flagship 2.5-hour whale watch on a custom-built sailing catamaran from Kāʻanapali Beach, with a chef-prepared island lunch, full open bar, marine naturalist, hydrophone and wide viewing decks and nets. Limited to 35 guests on a boat that normally carries far more, so there is room at the rail for everyone.
Maui's humpbacks spend the summer gorging on krill and herring from British Columbia to the Bering Sea. Then they stop eating and swim roughly 3,000 miles to breed and give birth in the shallow, predator-free water around Maui Nui.
Humpbacks are the most acrobatic of the great whales. Each move has a name and, usually, a meaning.
The first thing most people see. A humpback exhales about 90 percent of its lung volume in a fraction of a second, and the warm, oily breath condenses into a bushy column...
The showstopper. A 40-ton whale drives upward with two or three powerful tail strokes and clears most of its body before crashing back on its side. The slap carries for...
Humpback flippers are the longest of any whale, up to 15 feet, a third of the body. Rolling on its side or back, the whale lifts one or both and slaps them flat on the...
The whale hangs head-down, raises its flukes high and smacks them down, over and over. Where a breach says hello, a tail slap often says back off. Mothers lobtail when...
The most violent thing a humpback does at the surface. It whips the whole rear third of its body, the peduncle, sideways out of the water and slams it down on, or at,...
A surging push of the head above the surface, throat pleats showing, usually at speed and straight at a rival. Head lunges are the stuff of Maui's competition pods: a...
The stretch of Honoapiʻilani Highway between Māʻalaea and Lahaina is one of the best places in the world to watch whales without a boat. In peak season you will see blows from your car.

Maui whale season runs December through April. Peak season, when the ʻAuʻau Channel holds the most whales, is January through March. A few early whales show up in October and November and a few mothers and calves linger into May, but December is when the season really starts and the boats are out every day. West Maui tours run through mid or late April.
February. It has the highest counts in almost every year of the Great Whale Count and Sanctuary Ocean Count, and it is the month of World Whale Day on Maui. January and March are nearly as good. If you want fewer boats and calmer seas, late March and April are quieter but still full of mothers and calves.
Yes, easily, and West Maui is the best place on the island for it. The lookouts along the Honoapiʻilani Highway between Māʻalaea and Lahaina (Papawai Point and McGregor Point) sit high above the channel where the whales concentrate. Kāʻanapali Beach and the Kapalua Coastal Trail are also reliable in peak season. Bring binoculars and go in the morning when the water is glassy.
Most leave right off the sand at Kāʻanapali Beach, in front of Whalers Village, where a shuttle or the boat itself noses onto the beach. Mala Boat Ramp in north Lahaina is the other West Maui launch. Lahaina Harbor reopened for limited daytime commercial use in December 2025 after the 2023 fire, and a few operators have returned, but most West Maui whale watches still load at Kāʻanapali or Mala.
It depends on your group. A raft like Maui Whale Adventures’ twin-engine adventure boat puts you a few feet above the water with 20 or fewer people, covers more water quickly, and is the pick for photographers and anyone who wants to be close. A catamaran like Teralani’s gives you a stable, shaded deck, a bathroom, lunch and an open bar, and is the better choice for grandparents, toddlers, and people who get seasick. Both run naturalists and hydrophones and both guarantee sightings.
Federal law makes it illegal to approach a humpback whale closer than 100 yards (300 feet) in Hawaiian waters, by boat, kayak, paddleboard or swimming, and 1,000 feet by aircraft. Whales, however, can approach you. When a curious whale surfaces next to a boat the captain puts the engines in neutral and waits, and these muggings are the encounters people remember for life.
Both operators load from the sand at Kāʻanapali Beach, run certified naturalists and hydrophones, and guarantee you will see whales. Pick the one that fits your group.
