The edge of the continental shelf lies closer to the Wildcoast than almost anywhere else in South Africa. The region is therefore much affected by the warm Agulhas current, which brings warm water and tropicals down the coast, whilst seasonal fluctuations cause a colder counter-current to move north bringing cold water species to the area - see sardine run.

The waters off the Transkei are relatively unexplored despite the areas fascinating history of wrecks and attempted salvage. The coastline itself is mostly undeveloped and difficult to access. Numerous rivers deposit murky waters along the shore during the rainy season and for this reason the diving is often best in winter. Rough seas also pose some challenges and divers can expect surge on most sites. However, when conditions are right, the diving can be spectacular and the areas unique location - at the transition between tropical and temperate waters - will bring great rewards to the more adventurous.

As yet, the Wildcoast has little infrastructure for scuba diving. Equipment hire is limited to tanks and weights at best, so divers should ensure that they are as self-sufficient as possible. Oceans Africa are currently exploring the area - see tours for the latest updates.
