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

This image shows only the swells directed at Windansea that coincided with light winds or offshore conditions through a typical northern hemisphere autumn. It is based on 8724 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 red illustrates the biggest 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 longest spokes, was SW, whereas the the prevailing wind blows from the WNW. 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 50% of the time, equivalent to 46 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere autumn but 4% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 4%, equivalent to (4 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Windansea is exposed to open water swells, we think that that clean surf can be found at Windansea about 50% of the time and that surf is messed up by onshore wind 43% of the time. This is means that we expect 85 days with waves in a typical northern hemisphere autumn, of which 46 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.
