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

This image shows only the swells directed at Jongensfontein that coincided with light winds or offshore conditions through a typical May. It is based on 2696 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow represent increasing swell sizes and red shows highest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the most common swell direction, shown by the largest spokes, was SSW, whereas the the dominant wind blows from the W. 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 48% of the time, equivalent to 15 days. Open water swells exceeding >3m (>10ft) only arise 4% of the time in a typical May, equivalent to just one day but 18% of the time we expect swell in the range 2-3m (6.5-10ft) 18%, equivalent to (6 days). Taking into account the proportion of these swells that coincided with predicted 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 48% of the time and that surf is messed up by onshore wind 48% of the time. This is means that we expect 30 days with waves in a typical May, of which 15 days should be clean enough to surf.

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.
