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

This image shows only the swells directed at Kahului Harbor that coincided with light winds or offshore conditions through a typical northern hemisphere summer. It is based on 7266 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 show increasing swell sizes and red illustrates the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the dominant swell direction, shown by the largest spokes, was NE, 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 1.8% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere summer. 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 1.8% of the time and that surf is blown out by onshore wind 66% of the time. This is means that we expect 62 days with waves in a typical northern hemisphere summer, 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.
