K-38 Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at K-38 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 illustrate increasing swell sizes and red illustrates largest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the most common swell direction, shown by the largest spokes, was W, whereas the the most common wind blows from the NNW. 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 43% of the time, equivalent to 39 days. Open water swells exceeding >3m (>10ft) only happen 0.7% of the time in a typical northern hemisphere winter, equivalent to just one day but 12% of the time we expect swell in the range 2-3m (6.5-10ft) 12%, equivalent to (11 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that K-38 is exposed to open water swells, we estimate that clean surf can be found at K-38 about 43% of the time and that surf is messed up by onshore wind 55% of the time. This is means that we expect 89 days with waves in a typical northern hemisphere winter, of which 39 days should be clean enough to surf.

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.
