Cap Sim Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at Cap Sim that coincided with light winds or offshore conditions through a typical northern hemisphere winter. It is based on 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 represent increasing swell sizes and red illustrates the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the prevailing swell direction, shown by the largest spokes, was NW, whereas the the dominant wind blows from the NNE. 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 77% of the time, equivalent to 70 days. Expect open water swells to exceed >3m (>10ft) 10% of the time (9 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Cap Sim is exposed to open water swells, we think that that clean surf can be found at Cap Sim about 77% of the time and that surf is messed up by onshore wind 22% of the time. This is means that we expect 90 days with waves in a typical northern hemisphere winter, of which 70 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.
