James Kealoha Beach Park Swell Statistics, All Year: Surf with Light or Offshore Winds

This image shows only the swells directed at James Kealoha Beach Park that coincided with light winds or offshore conditions through a typical year. It is based on 34628 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 largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the most common swell direction, shown by the biggest spokes, was ENE, 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 22% of the time, equivalent to 80 days. Open water swells exceeding >3m (>10ft) only occur 0.3% of the time in a typical year, equivalent to just one day but 10% of the time we expect swell in the range 2-3m (6.5-10ft) 10%, equivalent to (36 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that James Kealoha Beach Park is exposed to open water swells, we calculate that clean surf can be found at James Kealoha Beach Park about 22% of the time and that surf is messed up by onshore wind 43% of the time. This is means that we expect 237 days with waves in a typical year, of which 80 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.
