Jongensfontein Swell Statistics, Winter: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Jongensfontein that coincided with light winds or offshore conditions through a typical southern hemisphere winter. It is based on 8738 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow represent increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the dominant swell direction, shown by the largest spokes, was SSW, whereas the the dominant wind blows from the WNW. The chart at the bottom shows the same thing but without direction information. For example, swells larger than 1.5 feet (0.5m) coincided with good wind conditions 51% of the time, equivalent to 46 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (5 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Jongensfontein is exposed to open water swells, we calculate that clean surf can be found at Jongensfontein about 51% of the time and that surf is spoilt by onshore wind 45% of the time. This is means that we expect 87 days with waves in a typical southern hemisphere winter, of which 46 days should be surfable.

IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
