Why Blue and Fin Whales Use the Benguela Coast Off Namibia

Stand on the Namibian shore and you see sand, fog and a dry, empty land. Look at the water instead. The cold Benguela current brings water full of nutrients up towards the surface, and that feeds a busy food web. So why do blue and fin whales come here? Most likely for food. Both species have been recorded along the South East Atlantic coast.

A 2026 study of long-term records from Namibia and South Africa reports a recent rise in sightings. It also warns that how much effort people put into looking may shape that pattern.

What is upwelling, and why does it matter for whales?

When winds push surface water away from the coast, colder water full of nutrients can rise from below. Those nutrients help plankton grow. Plankton feeds small animals, and small animals feed bigger predators.

The exact prey and feeding behaviour change with the species and the conditions. The simple version is this: a productive ocean can offer food for whales, even next to a landscape that looks dry and empty from the shore.

Why blue and fin whales?

Blue whales are the largest animals on Earth, and fin whales come close behind. Both are baleen whales that filter small prey from the water. They can travel very far, but a rich feeding area can draw them into a region.

The sightings do not make Namibia a guaranteed whale-watching stop. The whales may be far offshore, underwater or simply somewhere else when people are looking. Wildlife encounters are unpredictable. Whale watching should always follow local regulations and experienced professional guidance.

What the new records add

The researchers put together more than six decades of confirmed records. The rise in sightings is encouraging, but more people reporting is one possible reason for it. That is why a record of observations has to be read carefully.

The useful next step is steady monitoring. More years of data will help researchers tell real population changes apart from changes in how often people search and report.

The Benguela coast is not just scenery. It is a living feeding ecosystem, shared by whales, seals, dolphins, seabirds, fishers and ships. The cold water is part of the story. Let the animals use it on their own terms, and give them room.

Questions people ask

Wildlife encounters are never guaranteed and never forced. Ocean Calling works only with vetted, ethical local operators, and every animal is free to approach, or not, entirely on its own terms.
