The Incredible Migration of Humpback Whales

Aliwal Shoal: The Ultimate Whale-Watching Destination

South Africa boasts an impressive 3200 km coastline with unique geographical features and diverse marine life. Among the highlights of visiting during the winter season is witnessing the spectacular migration of humpback whales. These magnificent creatures embark on their annual northward journey after spending four months feeding in the nutrient-rich waters of Antarctica, with Aliwal Shoal standing out as the premier location to observe this incredible phenomenon.

Aliwal Shoal offers an unparalleled vantage point for whale watchers and scuba divers. Located off the coast of KwaZulu-Natal, this marine area is renowned for its rich biodiversity. It is a prime spot to witness humpback whales (Megaptera novaeangliae) in their natural habitat. Known for their acrobatic behaviour and complex songs, these large, migratory baleen whales are characterised by their long pectoral fins, knobby heads, and distinctively humped backs, which give them their name.

Humpback whales undertake one of the longest migrations of any mammal, travelling up to 25,000 kilometres (16,000 miles) annually. From June to November, these majestic creatures can be seen along the South African coast, including the waters around Aliwal Shoal. They migrate from their feeding grounds in the cold polar regions to the warmer tropical and subtropical waters, where they mate and give birth. The coastline near Aliwal Shoal is a crucial part of their migratory route, offering frequent sightings of breaching, tail-slapping, and other surface behaviours.

Humpback whales are renowned for their complex and haunting songs, believed to play a role in communication and mating. These songs can last up to 20 minutes and are often repeated for hours. Their acrobatic displays, including breaching (leaping out of the water) and slapping their fins and tails on the water’s surface, make them a favourite among whale watchers.

Aliwal Shoal is the ultimate destination for those wanting to experience the wonder of humpback whale migration. Its unique location and abundant marine life provide an unforgettable experience, making it a must-visit spot for divers, marine enthusiasts and nature lovers.
