James Kealoha Beach Park Swell Statistics, June: 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 June. It is based on 2786 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 illustrates the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the dominant swell direction, shown by the largest spokes, was ENE, whereas the the prevailing 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 21% of the time, equivalent to 6 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal June but 15% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 15%, equivalent to (4 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that James Kealoha Beach Park is exposed to open water swells, we think that that clean surf can be found at James Kealoha Beach Park about 21% of the time and that surf is blown out by onshore wind 62% of the time. This is means that we expect 25 days with waves in a typical June, of which 6 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.
