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

This image shows only the swells directed at Ferrel that coincided with light winds or offshore conditions over a normal 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 represent increasing swell sizes and red shows biggest swells greater than >3m (>10ft). In each graph, 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 biggest spokes, was NW, whereas the the prevailing 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 35% of the time, equivalent to 10 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 Ferrel is exposed to open water swells, we calculate that clean surf can be found at Ferrel about 35% of the time and that surf is blown out by onshore wind 53% of the time. This is means that we expect 26 days with waves in a typical December, of which 10 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.
