Kawaihae Breakwater Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at Kawaihae Breakwater that coincided with light winds or offshore conditions over a normal October 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 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 represents the largest 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 dominant swell direction, shown by the largest spokes, was NW, whereas the the most common wind blows from the NNE. 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 6% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal October. Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Kawaihae Breakwater is slightly protected from open water swells, we calculate that clean surf can be found at Kawaihae Breakwater about 6% of the time and that surf is blown out by onshore wind 1.0% of the time. This is means that we expect 2 days with waves in a typical October, of which 2 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.
