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

This image shows only the swells directed at Bancoora that coincided with light winds or offshore conditions over a normal southern hemisphere autumn and is based upon 6580 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 illustrate increasing swell sizes and red represents biggest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the dominant swell direction, shown by the largest spokes, was SW, whereas the the prevailing 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 43% of the time, equivalent to 39 days. Open water swells exceeding >3m (>10ft) only arise 0.6% of the time in a typical southern hemisphere autumn, equivalent to just one day but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (3 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Bancoora is exposed to open water swells, we think that that clean surf can be found at Bancoora about 43% of the time and that surf is blown out by onshore wind 50% of the time. This is means that we expect 85 days with waves in a typical southern hemisphere autumn, of which 39 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.
