As of today, out of season, returns ~July. Earth Exhibit tracks the live conditions and flags it the moment it is on.
Each austral winter, humpback whales complete a migration of roughly 6,500 kilometers from their Antarctic feeding grounds into the warm waters of the South Pacific to breed, and Rarotonga in the Cook Islands sits squarely on the route.
What makes Rarotonga remarkable is geography: the island's fringing reef drops to deep water within meters of the coast, so the whales come in startlingly close to land.
From July to October — with September the peak — you can stand on the shore or a coastal lookout and watch mothers and calves, breaching adults, and the spray of blows just beyond the reef, sometimes only a stone's throw out.
On calm days you may even hear the boom of a breach or, with your head near the water, the long song of a male carrying through the sea.
Boat trips run too, but Rarotonga is one of the rare places where the whales put on the show from the beach.
The western and northern coasts, where the reef hugs the land closest, are the best vantage.
