Witzigs Swell Statistics, Spring: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Witzigs that coincided with light winds or offshore conditions over a normal southern hemisphere spring and is based upon 8476 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 largest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the largest spokes, was SW, 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 33% of the time, equivalent to 30 days. Open water swells exceeding >3m (>10ft) only arise 0.8% of the time in a typical southern hemisphere spring, equivalent to just one day but 12% of the time we expect swell in the range 2-3m (6.5-10ft) 12%, equivalent to (11 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Witzigs is exposed to open water swells, we estimate that clean surf can be found at Witzigs about 33% of the time and that surf is blown out by onshore wind 65% of the time. This is means that we expect 89 days with waves in a typical southern hemisphere spring, of which 30 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.
