Waimea Bay/Pinballs Swell Statistics, December: 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 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 illustrate increasing swell sizes and red shows the highest swells, greater than >3m (>10ft). In each graph, 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 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 51% of the time, equivalent to 15 days. Expect open water swells to exceed >3m (>10ft) 11% of the time (3 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Waimea Bay/Pinballs is exposed to open water swells, we calculate that clean surf can be found at Waimea Bay/Pinballs about 51% of the time and that surf is messed up by onshore wind 14% of the time. This is means that we expect 20 days with waves in a typical December, of which 15 days should be surfable.

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.
