La Concha Swell Statistics, Winter: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at La Concha that coincided with light winds or offshore conditions through a typical northern hemisphere winter and is based upon 7765 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 biggest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was WNW, whereas the the prevailing wind blows from the SSW. 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 48% of the time, equivalent to 44 days. Expect open water swells to exceed >3m (>10ft) 4% of the time (4 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that La Concha is exposed to open water swells, we calculate that clean surf can be found at La Concha about 48% of the time and that surf is blown out by onshore wind 47% of the time. This is means that we expect 86 days with waves in a typical northern hemisphere winter, of which 44 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.
