Sydney’s spectacular sandstone coastline is also a humpback whale highway and if you plan to visit Sydney Harbour between May and October, it’s a veritable playground for whales of all kinds including humpbacks, orcas, southern right whales and minke. Whale watching with Captain Cook Cruises also offers full commentary as well as their unique whale watching guarantee, which means if you don’t see a whale, you cruise again for FREE! Combine the sights of Sydney Harbour with an open water cruise through the entrance of Sydney Harbour to find the gentle giants of the sea. The cruises are safe, comfortable, spacious and best of all, whale numbers are expected to break all records! Humpback Whale sightings have continued to increase over the last decade. In June and July these majestic marine mammals migrate north for breeding before returning south with their calves from September to November. Southern Right Whales do not migrate, instead moving along the coast finding protected shelters for their young. Occasionally a mother and calf make Sydney Harbour their home for a short while and thousands of locals come out to wish them well. Very rarely a whale is not spotted during the cruise. In this case your Whale Guarantee entitles you to another free cruise during the same season on a standby basis.
