K-181 Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at K-181 that coincided with light winds or offshore conditions over a normal northern hemisphere winter. It is based on 6931 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 represent 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 frequently that size swell occurs.

The diagram suggests that the prevailing swell direction, shown by the biggest spokes, was WNW, whereas the the prevailing wind blows from the NW. 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 33% of the time, equivalent to 30 days. Open water swells exceeding >3m (>10ft) only happen 1.0% of the time in a typical northern hemisphere winter, equivalent to just one day but 15% of the time we expect swell in the range 2-3m (6.5-10ft) 15%, equivalent to (14 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that K-181 is exposed to open water swells, we think that that clean surf can be found at K-181 about 33% of the time and that surf is spoilt by onshore wind 65% of the time. This is means that we expect 89 days with waves in a typical northern hemisphere winter, of which 30 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.
