The world’s oceans are governed by the Coriolous Effect. In the northern hemisphere major oceanic currents tend to run in a clockwise direction and in the southern hemisphere they tend to turn in a counter-clockwise direction. South Africa being at the very tip of the African continent is unique in that it has a mixture. On the east coast the Agulhas Current runs from north to south and on the west coast the Benguela Current runs from south to north.  Off the tip off the Cape of Good Hope there is a confluence of these two currents, the colder Benguela Current tends to have lower visibility, the warmer Agulhas Current tends have better visibility so not surprisingly the Agulhas Current is the more popular choice for drift dives.

In June 2015 Mick Todd and I and the rest of an Andy Murch Big Fish Expeditions group boarded Explorer 1 and journeyed roughly 47 kilometres south from the Cape of Good Hope in the Agulhas Current looking for good underwater visibility and we got it. A buoy was deployed and a 20 litre container suspended 10 metres beneath it to give divers a visual reference point. Then we all jumped in taking care to always keep within visual range of the crate as we drifted in the blue for approximately one kilometre. As soon as we had hit the water, we were immediately surrounded by up to a dozen Blue Sharks and Yellowfin Tuna and after a while, an inquisitive Seal. A really enjoyable drift dive.
