Kohala Lighthouse Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at Kohala Lighthouse that coincided with light winds or offshore conditions through a typical northern hemisphere winter. It is based on 8485 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow show increasing swell sizes and red shows largest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the dominant swell direction, shown by the longest spokes, was NNW, whereas the the most common wind blows from the E. 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 13% of the time, equivalent to 12 days. Open water swells exceeding >3m (>10ft) only arise 0.7% of the time in a typical northern hemisphere winter, equivalent to just one day but 2% of the time we expect swell in the range 2-3m (6.5-10ft) 2%, equivalent to (2 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Kohala Lighthouse is exposed to open water swells, we think that that clean surf can be found at Kohala Lighthouse about 13% of the time and that surf is messed up by onshore wind 31% of the time. This is means that we expect 40 days with waves in a typical northern hemisphere winter, of which 12 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.
