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

The rose diagram shows only the swells directed at James Kealoha Beach Park that coincided with light winds or offshore conditions through a typical December. It is based on 2705 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 show increasing swell sizes and red illustrates 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 prevailing swell direction, shown by the largest spokes, was ENE, whereas the the dominant wind blows from the ESE. 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 28% of the time, equivalent to 8 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal December but 23% of the time we expect swell in the range 2-3m (6.5-10ft) 23%, equivalent to (7 days). Taking into account the ratio 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 28% of the time and that surf is messed up by onshore wind 29% of the time. This is means that we expect 17 days with waves in a typical December, of which 8 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.
