This is what you would call a whale of a deviation!  Popular Science is reporting Humpback whales are organizing in huge numbers, and no one knows why.  The numbers are huge and so are the whales.  The pacific northwest natives can grow to 50 feet in length and weigh 40 tons. http://biganimals.com/10-facts-about-humpback-whales/

Scientists say Humpback whales are normally pretty solitary --calling herds of 10 to 20 "large" but now they're congregating in groups of 20 to 200 off the coast of South Africa.

In fact, Humpback whales aren't supposed to be hanging out in that region at all, typically Humpbacks would be feeding in the icy waters of Antarctica this time of year.

Normally, humpback whales spend their summer months feeding off the coast of California to Alaska, then migrating to the warm waters of Hawaii, Mexico, Costa Rica and Japan to give birth.

Something is up with the Humpbacks but science doesn’t know what!  Their observations are published in the March science journal Polsone.
