Afrikaans name: Aliwal-bank
The little town of Umkomaas, on the KwaZulu-Natal south coast, is the base for access to one of South Africa’s best known natural attractions. This is where divers gather from all over South Africa and many overseas countries to visit Aliwal Shoal. The dive site is about 5 km offshore and slightly south of Umkomaas.
There are many things that attract divers to Aliwal Shoal, but the conditions are not always favourable nor are they predictable. The rivers flowing into the Indian Ocean along the south coast bring with them a lot of silt, especially when in flood. If the sea is rough it picks up this silt causing murky water conditions.
So, I have mentioned the negative side of Aliwal Shoal, so what is the attraction? The reef has some spectacular underwater scenery and, during winter, is the gathering place for Raggedtooth Sharks.
The water depth varies from 9 metres to 30 metres and the water temperature is normally in the high teens to low twenties. The reef runs for approximately 3 km and is 300 metres wide in parts.
The marine life includes a variety of hard and soft corals, invertebrates, turtles, fish of all sizes including the massive Whale Shark and the sharks. As mentioned above there are at times large gathering of Raggedtooth Sharks, but you may also see a Zambezi Shark. Care should be taken around the sharks, in particular the latter species which is more aggressive than the former.
