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

This image shows only the swells directed at Woolamai that coincided with light winds or offshore conditions through a typical southern hemisphere autumn. It is based on 8682 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 biggest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the dominant swell direction, shown by the longest 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 38% of the time, equivalent to 35 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal southern hemisphere autumn but 7% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 7%, equivalent to (6 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Woolamai is exposed to open water swells, we calculate that clean surf can be found at Woolamai about 38% of the time and that surf is messed up by onshore wind 57% of the time. This is means that we expect 86 days with waves in a typical southern hemisphere autumn, of which 35 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.
