Kahului Harbor Swell Statistics, Settembre: Surf with Light or Offshore Winds

This image shows only the swells directed at Kahului Harbor that coincided with light winds or offshore conditions over a normal September and is based upon 2400 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 represent increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the most common 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 5% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal September. Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Kahului Harbor is exposed to open water swells, we estimate that clean surf can be found at Kahului Harbor about 5% of the time and that surf is messed up by onshore wind 76% of the time. This is means that we expect 24 days with waves in a typical September, of which 2 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.
