Humpback Whales - The World’s Best Places for Whale Watching and Swimming

21st September 2016   |   Mario Passoni

Humpback whales (Megaptera novaeangliae) are among the most beautiful and friendly whales on our planet. There are many places to encounter these gentle giants, and the opportunity to swim with them is quite common.

Their scientific name, "Megaptera", refers to their large pectoral fins, which are in fact the largest limbs of any creature in nature. They were first given the second part of their name in New England. One of the most impressive features of humpback whales is that they “sing" underwater, emitting sounds that are thought to serve as communication with other individuals. It’s now understood that by making these noises, the whales are trying to find a mate for reproduction or mark their territory.

Humpback whales are migratory animals. During the polar summer, they feed on plankton and small fish, but when the temperatures begin to decrease, they move to tropical seas to mate and breed.

Humpback whales are the only baleen whales that jump completely out of the water (breaching). They also show a repertoire of at least 15 different surface behaviors, giving them the title of the most acrobatic whale.

The Best Places for Whale Watching

The following are the world’s best places to watch humpback whales in their natural habitat.

Saguenay - St. Lawrence Marine Park, Québec

This marine park was created to protect and support the more than 1,600 marine species living there, including a resident population of beluga whales. There are 13 species of whales that visit the Marine Park in order to feed and build their energy reserves for the long migrations ahead. Excursions can be made using big vessels, small rubber boats or even kayaks. As always, it’s important to maintain the required distance (650 feet [200 meters] from humpback whales) in order to avoid disturbing them.

Whales can be seen breaching from shore, but to have the best experience, just hop on a small boat with a marine biologist on board. You’ll be able to get a lot closer to the whales, an experience you’ll never forget.

Maui, Hawaii

Humpback whales start to arrive in these crystal clear waters in December, but peak numbers occur in mid-January. You can see them right from the beach, a few miles away, but of course we recommend participating in an excursion with experts. In the span of a couple of hours, you’ll be able to approach these whales as close as 100 yards (90 meters) legally. Preferred tours depart in the morning, because at this time, it is less windy.

However, Alaska's cold waters are rich in food, and these whales spend their time here accumulating fat for their next migration.

Best Time: June to Early September

Hervey Bay, Australia

Humpback whales stop annually in these Australian waters, because Hervey Bay is along their migration route to Antarctica. Here they can grow their young in the absence of predators. There are many boats offering whale watching tours, which last an average of four hours. As a special treat, the vessels are often equipped with a hydrophone for listening to the songs of whales.

Scuba diving with humpback whales

The Best Places for Scuba Diving with Whales

Diving is generally not allowed with whales as the bubbles produced can be interpreted by these cetaceans as a sign of aggression or danger. They can emit bubbles as well from their blowhole. This regulation also serves to limit the disturbance of the whales in their nursing areas.
