South Africa is one of the worlds best surf destinations with 3,000km (1,900mi) of coastline split between the Atlantic and Indian Oceans. Despite better waves elsewhere in South Africa, Durban has become the country's surf centre because of a high population density of surfers and a great year round climate. South swells wrap around the Bluff Peninsula, and focus on the long piers and groynes that punctuate the coastline. When the conditions are right, then powerful, hollow beachbreaks are the result. There are a few reefs to consider including the world class tubes of Cave Rock. Most Natal spots are best on low to mid tides with light offshore winds, which unfortunately, are rare. Many foreign surfers coming to South Africa have sharks at the top of their mind, however Durban has not had a single attack since shark nets were put in place in 1962.
