It completes the anticyclonic gyre of the South Indian Ocean, and because the African continent terminates at a relatively modest latitude, it becomes a mechanism for the climatologically important inter-ocean exchange between the Indian and Atlantic Oceans. The south-westward flowing Agulhas Current only becomes fully constituted along the east coast of southern Africa at a latitude somewhere between Durban (South Africa) and Maputo (Mozambique). It increases in speed and volume flux downstream.

On average, its volume flux is 70 × 106 m.3/s, with only small temporal changes. Its depth, by contrast, can vary from 6561 ft. (2,000 m.) to the sea floor at 9,842 ft. (3,000 m.) over a period of months. It is ...
