Similar to birds, humpback whales migrate seasonally for reasons of feeding and reproduction. The colder northern waters have the richest food supply, however it is too cold for young calves (baby whales), so the adults migrate to warmer waters to give birth, raise the young calves, and breed. Once the calves have grown enough and gained enough blubber to insulate themselves, the whales head north to feed again.

In the southern hemisphere they do it the other way round. They migrate north to the tropical waters to give birth and breed and then migrate south to Antarctic waters to feed.

And then they travel south to north in six months. They are going from feeding ground to feeding ground. Those locations are seasonally weather-dependent.

They can get more food in the colder north, but a warmer climate is better for giving birth and caring for a young calf.

good questions maybe cause the water temp.
