When is the best time to see Whales?
It's easy to see whales in the Cook Islands simply because the whales come right up to the Island. You can often see them playing in the water off the shore, scratching their backs and breaching out of the water. Humpbacks migrate into the South Pacific waters of Oceania from summer feeding grounds in the high latitude waters of the Southern Hemisphere. The largest migration is from July to October, so you don't even need to venture into the water to see them because they swim so close to shore. There are many diving and boating excursions that will take you to the best whale viewing areas.
