Cape Town is the second largest city in South Africa and is the capital of the Western Cape Province, as well as being the legislative capital of South Africa.
It is located in the south-west corner of the country near the Cape of Good Hope, and is the most southern city in Africa. It is a stone’s throw from South Africa’s world-famous Cape Wine lands around Stellenbosch, Paarl and Franschhoek.
Cape Town is located near two oceans, the Atlantic and the Indian Ocean. Because of the Benguela Current the Atlantic Ocean is relatively cold (about 8°C to 14°C). The Indian Ocean is warmer (12°C to 17°C), and here you can see the more colourful fish.
The official border between the two oceans is at Cape Agulhas, but currents and eddies take the warmer water futher west and these waters can reach the eastern side of the Cape Peninsula in False Bay, so from a diving point of view, the Cape Peninsula may be considered the interface between the two marine biological regions, and there is a notable difference in character between the waters of the two coasts of the peninsula.
This manifests itself in the different range of marine life found on the two coasts. These regions are the South Western Cape inshore bioregion and the Agulhas inshore bioregion.
