Backyards Swell Statistics, December: Surf with Light or Offshore Winds

This image shows only the swells directed at Backyards that coincided with light winds or offshore conditions through a typical December and is based upon 2457 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 represents the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was NNW, whereas the the most common 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 29% of the time, equivalent to 9 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 Backyards is exposed to open water swells, we think that that clean surf can be found at Backyards about 29% of the time and that surf is blown out by onshore wind 36% of the time. This is means that we expect 20 days with waves in a typical December, of which 9 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.
