Behind me is a lighthouse..here is some more info.

The sea off Cape Agulhas is notorious for winter storms and mammoth rogue waves, which can range up to 30 metres (100 ft) high and can sink even large ships. These conditions are caused by a number of factors. The naturally strong winds of the roaring forties, which blow from west to east, and the cold Antarctic Circumpolar Current flowing in the same direction, come up against the warmer Agulhas Current in the region of the cape. These conflicting currents of water of different densities, and the west winds blowing against the Agulhas Current, can create extremely hazardous wave conditions; these are further exacerbated by the shallow waters of the Agulhas Bank, a broad, shallow part of the continental shelf which juts 250 kilometres (155 mi) south from the cape, after which it falls steeply away to the abyssal plain.

These hazards have combined to make the cape notorious among sailors. The coast here is littered with wrecks: Arniston (1815), Cooranga (1964), Elise (1879), European (1877), Federal Lakes (1975), Geortyrder (1849), Gouritz (1981), and Gwendola (1968) are just a few of the vessels lost in the proximity of the "Cape of Needles." Owing to the hazards and following the loss of several vessels, notably the Arniston, a lighthouse was built in 1848, this being only the second one to be built in the country.
South of Cape Agulhas the warm Agulhas Current that flows south along the east coast of Africa retroflects back into the Indian Ocean. While retroflecting, it pinches off large ocean eddies (Agulhas rings) that drift into the South Atlantic Ocean and take enormous amounts of heat and salt into the neighboring ocean. This mechanism constitutes one of the key elements in the global conveyor belt circulation of heat and salt.

Unlike its better-known relative, the Cape of Good Hope, Cape Agulhas is relatively unspectacular, consisting of a gradually curving coastline with a rocky beach. A survey marker indicates the location of the cape, which would otherwise be difficult to identify. The waters of the Agulhas Bank off the coast are quite shallow and are renowned as one of the best fishing grounds in South Africa.

The rocks that form Cape Agulhas belong to the Table Mountain Group, often loosely termed the Table Mountain sandstone. They are closely linked to the geological formations that are exposed in the spectacular cliffs of Table Mountain, Cape Point, and the Cape of Good Hope.
