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

The rose diagram shows only the swells directed at Kohala Lighthouse that coincided with light winds or offshore conditions over a normal August and is based upon 2976 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 either graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the dominant swell direction, shown by the largest spokes, was ENE, whereas the the prevailing 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 0% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal August. Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Kohala Lighthouse is exposed to open water swells, we estimate that clean surf can be found at Kohala Lighthouse about 0% of the time and that surf is messed up by onshore wind 7% of the time. This is means that we expect 2 days with waves in a typical August, of which 0 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.
