Experience the magic of whale watching in Maui from January 15 through March 31st

Each whale species has its own distinct behavioral traits, and the humpback whales are most often noted for their elegant and unique songs. Males are the singers of the species and have been found to sing the same series of notes, which can span up to 8 octaves, as other males in the group, with subtle changes year after year. Researcher believe this is done as both a mating call and way of communicating with other males

When you’re in Hawaii, make sure to keep an eye out for some of the most common humpback whale behaviors, including:

Every year at the start of Fall more than 60% of the North Pacific Humpback Whale population will begin their migration from Alaska to Hawaii, with many of them choosing to stay in the waters off of Maui during their visit.

Maui is considered by many to be the epicenter for whale watching in the Hawaiian Islands.

Whale watching season generally runs from December through April, when the tropical waters off Maui’s South coast are teeming with North Pacific Humpback Whales. However, our tours start at the beginning of January, guaranteeing whale sightings!

Kelly and Sean of Redline took us out whale watching. I loved that there were only around 12 adults on the boat. I appreciated the way Sean would gently turn the boat around so that everyone got a really good look. We had some terrific activity, whale-wise. Kelly’s knowledge was really appreciated. I highly recommend!!!

Sally B- Oregon, Bend

Had an awesome outing with Seth and Alex. They showed us a good time and kept the schedule loose. We had lots of time in each spot and saw a bit of everything. Redline supplied loads of food and drink as well as complimentary wet suits for anyone that wanted one. A top notch experience!

John H- CA, Saskatchewan

We took the five hour snorkeling trip to Molokini, etc and had a great trip!  We spotted a whale shark on the backside of Molokini and so many whales!  They even went out of the way to follow a pair having fun with some fin slaps and breaching. Great trip- thanks to Seth and Alex for everything!

Bridget W- IN, Indianapolis

We booked the 10:00 am whale watching tour for our family of four. We really enjoyed Captain Andy and Sean and how informative they were. We came up on a momma and baby, who swam right under our boat. It was amazing, an experience we will always remember. Thank you!

Williska- Portland

Not only will you return from your whale watching adventure with priceless photos and with more knowledge of these majestic marine mammals, you’ll also have made everlasting memories and had the time of your life.

    The humpback whales that migrate to the Hawaiian waters each year (seen on all Maui whale watching tours) spend their summers in Alaska. In the pre-whaling days, the pods were estimated in numbers upwards of 45,000 individuals. But as a result of commercial whaling, those numbers were down to just 1,400 humpbacks in 1966.


    The 1970s brought with it many of the marine-life protections we enjoy on this tour, including the endangered species and marine protection acts as well as international treaties. The humpback whales we will see on our whale watch tours range in size from 25-40 ton adults to 1 ton newborns.

    Although humpback whales aer found in oceans throughout the world, the population in the Arabian Sea is the only one that does not migrate.

    The saying “Thar she blows!” originated when whaling ships would see the spray of a blowhole during the height of the whaling industry.

    Humpback whales are protected under the Endangered Species Act of 1973 and Marine Mammal Prtection Act, Under this, it is illegal to harass, injure or kill a humpback whale in U.S. waters.

    The scientific name for humpback whales, Megaptera novaeangliae, means “Great wings of New England” due to the enormous size of their pectoral fins.
