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

This image shows only the swells directed at La Arena that coincided with light winds or offshore conditions through a typical northern hemisphere winter. It is based on 8485 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 red shows the largest 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 WNW, whereas the the most common wind blows from the WSW. 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 30% of the time, equivalent to 27 days. Expect open water swells to exceed >3m (>10ft) 3% of the time (3 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that La Arena is slightly protected from open water swells, we estimate that clean surf can be found at La Arena about 30% of the time and that surf is messed up by onshore wind 58% of the time. This is means that we expect 80 days with waves in a typical northern hemisphere winter, of which 27 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.
