Arniston Swell Statistics, Dicembre: Surf with Light or Offshore Winds

This image shows only the swells directed at Arniston that coincided with light winds or offshore conditions over a normal December and is based upon 2705 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 show increasing swell sizes and red represents the highest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the most common swell direction, shown by the biggest spokes, was SSW, whereas the the dominant 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 29% of the time, equivalent to 9 days. Expect open water swells to exceed >3m (>10ft) 5% of the time (2 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Arniston is exposed to open water swells, we estimate that clean surf can be found at Arniston about 29% of the time and that surf is spoilt by onshore wind 56% of the time. This is means that we expect 26 days with waves in a typical December, of which 9 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.
