Waimea Bay/Pinballs Swell Statistics, April: Surf with Light or Offshore Winds

This image shows only the swells directed at Waimea Bay/Pinballs that coincided with light winds or offshore conditions over a normal April and is based upon 2640 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 highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the prevailing swell direction, shown by the largest spokes, was NNW, 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 42% of the time, equivalent to 13 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal April but 31% of the time we expect swell in the range 2-3m (6.5-10ft) 31%, equivalent to (9 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Waimea Bay/Pinballs is exposed to open water swells, we think that that clean surf can be found at Waimea Bay/Pinballs about 42% of the time and that surf is messed up by onshore wind 10% of the time. This is means that we expect 16 days with waves in a typical April, of which 13 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.
