Humpback whale season in Rarotonga

Two humpback whales in Rarotonga

Winter is humpback whale season in Rarotonga. Every year, humpback whales take on a 4000 mile journey from their feeding grounds in the colder polar waters of the Southern Ocean to the warmer waters of the South Pacific islands, where they mate and give birth. Once the humpback whales leave their feeding grounds, the whales do not feed and rely totally on their fat reserves.

Humpback whales, Megaptera novaeangliae, are cetaceans and can weigh up to 40 tons and reach up to 19 meters. These giants are one of the larger rorqual species, which is the largest group of baleen whales. The rorqual, or Balaenopteridae family includes the minke whale and the blue whale, the largest animal on the planet.

The whale season in Rarotonga and the Cook Islands starts in July and goes until October. Most of the whale sightings in Rarotonga are usually in September, however this can vary from year to year.
