Kohala Lighthouse Swell Statistics, Settembre: 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 through a typical September and is based upon 2880 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 represents the highest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the prevailing swell direction, shown by the largest spokes, was NNE, whereas the the dominant 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 2% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal September. 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 estimate that clean surf can be found at Kohala Lighthouse about 2% of the time and that surf is messed up by onshore wind 24% of the time. This is means that we expect 8 days with waves in a typical September, of which 1 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.
