Each winter, South Africa’s coastline becomes part of one of the world’s great marine migrations, writes Miriam Kimvangu.

Between June and November, whales travel thousands of kilometres from the cold feeding grounds of Antarctica to the warmer waters of southern Africa, where they mate, calve and nurse their young.
For coastal towns and protected marine areas, the arrival of the whales signals the beginning of a seasonal spectacle that attracts travellers, photographers, researchers and conservationists alike. From the cliffs of the Western Cape to the subtropical coastline of KwaZulu-Natal, South Africa offers some of the best land-based whale watching in the world.
The species most commonly seen during the migration season is the southern right whale. Recognisable by its broad back, lack of dorsal fin and distinctive callosities on the head, the species often swims close to shore, making sightings accessible even without a boat tour. Humpback whales are also frequently seen moving along the coastline, especially on the eastern seaboard, while Bryde’s whales can be spotted in South African waters throughout the year.
Hermanus and Walker Bay
Hermanus remains South Africa’s most famous whale-watching destination and is widely regarded as one of the best land-based whale viewing sites globally. Located along the shores of Walker Bay, the town offers elevated cliff paths where southern right whales can often be seen breaching, spyhopping and nursing calves close to shore.The calm, sheltered waters of the bay create ideal conditions for mothers and calves during the breeding season. Peak whale activity generally occurs between August and October, although sightings often begin earlier in winter.
The nearby Walker Bay Nature Reserve provides a quieter alternative to the town centre. The reserve protects important coastal ecosystems, including limestone fynbos, dunes and marine habitats that support seasonal whale populations.
Hermanus is also home to the annual Hermanus Whale Festival, which combines environmental education, marine conservation awareness and tourism activities during peak whale season.
De Hoop Nature Reserve and Cape Agulhas
Further east, De Hoop Nature Reserve forms part of the De Hoop Marine Protected Area, one of the country’s most important coastal conservation zones. The reserve is known for hosting one of the largest concentrations of southern right whales along the South African coast during calving season. The reserve’s dunes overlook shallow bays where whales gather in significant numbers. Researchers and conservationists have long monitored the area because of its ecological importance for breeding populations.
Nearby Cape Agulhas, the southernmost point of Africa, also offers seasonal whale sightings. The meeting point of the Atlantic and Indian Oceans creates nutrient-rich waters that support diverse marine life throughout the year.
Stilbaai and the Garden Route coastline
Stilbaai plays an important role during whale calving season. The bay’s shallow and relatively sheltered waters provide a safer environment for mothers and calves, which are often seen resting close to shore. Unlike some busier whale-watching destinations, Stilbaai offers a quieter and more observational experience. Visitors can often spot whales from beaches, river mouths and coastal viewpoints without large crowds.
The broader Garden Route coastline also experiences seasonal whale movement. Areas near Wilderness, Plettenberg Bay and Mossel Bay occasionally provide sightings during migration periods, particularly during calm winter mornings.
The Eastern Cape migration route
The Eastern Cape forms an important part of the migration corridor used by both southern right and humpback whales. Jeffreys Bay is better known internationally for surfing, but winter and spring also bring opportunities to observe whales offshore. Humpback whales are commonly seen travelling along the coastline during migration, while southern right whales occasionally rest in calmer bays.
Further along the coast, Kenton-on-Sea offers estuaries, dune systems and elevated viewpoints that create ideal land-based observation areas. The relatively undeveloped coastline allows for quieter wildlife encounters and reduced marine disturbance.
KwaZulu-Natal’s whale coast
KwaZulu-Natal’s coastline is most strongly associated with humpback whale migration. These whales travel north during winter to breed in warmer tropical waters before returning south later in the year. iSimangaliso Wetland Park, South Africa’s first UNESCO World Heritage Site, protects a wide range of coastal and marine ecosystems that support migrating marine life. Offshore sightings of humpback whales are relatively common during peak migration months.
Nearby Cape Vidal provides elevated viewpoints where whales can occasionally be seen breaching offshore. The area’s combination of marine biodiversity, coastal forests and protected beaches makes it one of the province’s most ecologically significant coastal destinations.
Durban’s coastline also marks the return of the annual Welcoming of the Whales Festival 2026, hosted by the Sodurba Community Tourism Organisation. Taking place at WESSA Treasure Beach and Anstey’s Square on the Bluff, the event celebrates the arrival of migrating whales through educational talks, family activities and conservation-focused programming.
The festival highlights the growing role of marine education and community tourism in protecting South Africa’s coastal ecosystems. Events like these encourage greater awareness of whale conservation, responsible tourism practices and the environmental importance of migration corridors.
Why whale migration matters
Whale migration is an important ecological process. Whales contribute to marine ecosystem health through nutrient cycling and ocean biodiversity. Their recovery in South African waters also reflects decades of international conservation efforts following the end of commercial whaling. Today, many coastal protected areas and marine reserves play a critical role in safeguarding breeding grounds and migration routes. Responsible whale watching, whether land-based or boat-based, remains essential to reducing stress on marine animals during sensitive breeding and calving periods.
