James Kealoha Beach Park Swell Statistics, Winter: 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 over a normal northern hemisphere winter and is based upon 7765 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 shows highest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the most common swell direction, shown by the largest spokes, was NE, 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 21% of the time, equivalent to 19 days. Open water swells exceeding >3m (>10ft) only happen 1.1% of the time in a typical northern hemisphere winter, equivalent to just one day but 16% of the time we expect swell in the range 2-3m (6.5-10ft) 16%, equivalent to (15 days). Taking into account the ratio of these swells that coincided with predicted 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 21% of the time and that surf is spoilt by onshore wind 23% of the time. This is means that we expect 40 days with waves in a typical northern hemisphere winter, of which 19 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.
