WARNING FORECAST NOTES

All wind speeds are in km/h.
Wind speeds quoted are the expected average speeds. Individual gusts may exceed these values by a factor of 1.5.
Wave heights are given in metres.
Wave heights are significant wave height, which may be accompanied by individual waves 1.5 to 2.0 times higher.
No sea state prediction is given if the expected wave heights are less than 2 meters.
These estimates of winds and waves do not take into account the enhancing effects of the Agulhas Current off the South African east coast.
