Angourie Point Swell Statistics, All Year: Surf with Light or Offshore Winds
This image shows only the swells directed at Angourie Point that coincided with light winds or offshore conditions over a normal year and is based upon 28044 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow illustrate increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how frequently that size swell was forecast.
The diagram suggests that the dominant swell direction, shown by the largest spokes, was E, whereas the the prevailing wind blows from the SE. 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 18% of the time, equivalent to 66 days. Open water swells exceeding >3m (>10ft) only occur 0.3% of the time in a typical year, equivalent to just one day but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (11 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Angourie Point is exposed to open water swells, we think that that clean surf can be found at Angourie Point about 18% of the time and that surf is blown out by onshore wind 39% of the time. This is means that we expect 208 days with waves in a typical year, of which 66 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.
