El Capitan Swell Statistics, Dicembre: Surf with Light or Offshore Winds

This image shows only the swells directed at El Capitan that coincided with light winds or offshore conditions through a typical December. It is based on 2953 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 both graphs, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the most common swell direction, shown by the largest spokes, was WNW, whereas the the dominant wind blows from the NNW. 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 71% of the time, equivalent to 21 days. Expect open water swells to exceed >3m (>10ft) 5% of the time (2 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that El Capitan is slightly protected from open water swells, we estimate that clean surf can be found at El Capitan about 71% of the time and that surf is messed up by onshore wind 20% of the time. This is means that we expect 27 days with waves in a typical December, of which 21 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.
