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

This image shows only the swells directed at Jongensfontein that coincided with light winds or offshore conditions over a normal southern hemisphere autumn and is based upon 8682 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and red represents the largest swells, greater than >3m (>10ft). In either 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 biggest spokes, was SSW, whereas the the most common wind blows from the SSE. 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 34% of the time, equivalent to 31 days. Expect open water swells to exceed >3m (>10ft) 2% of the time (2 days). Taking into account the proportion 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 34% of the time and that surf is spoilt by onshore wind 60% of the time. This is means that we expect 86 days with waves in a typical southern hemisphere autumn, of which 31 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.
