Gale force winds in the bay are common in Sept/Oct

The months of September and October in the Bay are usually windy with some gale force wind storms bringing into the Bay high seas and spectacular sights.  On Sept 1, 2008, gale force winds combined with high tides and the solstice caused swells of between seven to 12 metres into the bay….causing damages to the shore and infrastructures. 

Almost a year later, on Oct 27, 2009, winds as high as 150km/hour hit the bay in the night, causing major damages to the Yacht Club marina and along the shore.

World Rhino day

The 22nd is “world rhino day”, and the WWF is calling for an end to rhino poaching, which as you all know (!) threatens the survival of the rhino.  South Africa which has most of the species in the world, has recently increased its protection policy with more severe prosecuting and sentencing. Nevertheless, numbers reported in the Press are indicating 287 rhinos decimated for the use of their horns, 16 or more of which were the endangered black rhino.

“This action must be met with a corresponding commitment by countries in Asia where consumer demand for rhino horn is inciting poachers” (source:

Did you know?: The Dolos

The “dolos” is an unusually-shaped concrete block of up to 30 tons, invented in East London, South Africa, in 1963, and found in millions around the world where protection from the effects of rough seas, current and tides is required, i.e. at harbour walls, breakwaters, shore earthworks. So, to protect a kilometer of coastline, about 10 000 dolosse (plural of “dolos”) are required.

The name “dolos” finds its origin in the Afrikaans word ‘dobbel osse’ (knucklebone), which is believed to refer to ox knuckle-joint bones used either in divination practices by sangomas, or to the knuckle bones game used by African children many years ago.

Dolosse can be found in the harbours of Durban, Port Elizabeth, St Francis, and many others outside South Africa such as on the Humboldt, the breakwaters of California, New Jersey, Hawaii, the High Island Reservoir East Dam in Hong Kong etc. The biggest dolosse can be found at the Ngqura deep water harbour of Port Elizabeth, where 26500 dolosse weighing each 30 tons make the upper layer of the 2.5km-long breakwater.
