Arniston Swell Statistics, Marzo: 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 March. It is based on 2964 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 each graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was SSW, whereas the the prevailing 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 32% of the time, equivalent to 10 days. Open water swells exceeding >3m (>10ft) only occur 4% of the time in a typical March, equivalent to just one day but 20% of the time we expect swell in the range 2-3m (6.5-10ft) 20%, equivalent to (6 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 think that that clean surf can be found at Arniston about 32% of the time and that surf is spoilt by onshore wind 58% of the time. This is means that we expect 28 days with waves in a typical March, of which 10 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.
