The KwaZulu-Natal (KZN) Bight is a sheltered embayment on South Africa’s east coast, bordered by Richards Bay in the north and Durban in the south, where valuable Marine Protected Areas (MPA) have been designated. As the Agulhas Current reaches Richards Bay, it becomes unstable, forming frontal eddies along its shoreward edge. These eddies, known locally as Natal Pulses and Durban Eddies, play a key role in regional ocean dynamics. While Natal Pulses have been well studied due to their large size and long lifespans, Durban Eddies have received less attention—largely due to limitations such as cloud cover and coarse spatial resolution associated with satellite observations and in-situ measurements. To address this, we use a high-resolution (1 km) ocean model to investigate the generation, structure, and evolution of these eddies. Our simulation reveals that Durban Eddies are semi-permanent features that occur frequently in the KZN Bight. We identify two distinct types: stationary eddies that remain trapped within the bight, and propagating eddies that detach and move downstream. The latter are larger, more intense, and more frequent than their stationary counterparts. A case study of a propagating eddy shows that it originates from the inshore frictional boundary layer of the Agulhas Current. After detaching from the KZN Bight, the eddy interacts with both the coastline and the Agulhas Current, causing it to break apart and eventually dissipate. The eddy is surface-intensified, with strong cyclonic circulation and uplifted isopycnals at its core. The domed isopycnals, combined with a high Richardson number, bring cold, nutrient-rich water to the surface, where it mixes with coastal waters and supports primary production. Given their frequent occurrence and physical influence, Durban Eddies likely play an important role in shaping the coastal environment, particularly by driving nutrient supply and enhancing biological productivity along the east coast where valuable MPA’s have been designated.
