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

This image shows only the swells directed at Allisons that coincided with light winds or offshore conditions over a normal southern hemisphere spring. It is based on 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 illustrate increasing swell sizes and highest 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 was forecast.

The diagram implies that the dominant swell direction, shown by the largest spokes, was WSW (which was the same as the dominant wind direction). 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. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal southern hemisphere spring 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 ratio of these swells that coincided with forecast offshore winds, and given the fact that Allisons is exposed to open water swells, we estimate that clean surf can be found at Allisons about 34% of the time and that surf is spoilt by onshore wind 61% of the time. This is means that we expect 86 days with waves in a typical southern hemisphere spring, of which 31 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.
