Cap Sim Swell Statistics, November: 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 November. It is based on 2867 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow show increasing swell sizes and red represents 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 most common swell direction, shown by the biggest spokes, was NNW, whereas the the dominant wind blows from the N. 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 74% of the time, equivalent to 22 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (2 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Cap Sim is exposed to open water swells, we calculate that clean surf can be found at Cap Sim about 74% of the time and that surf is blown out by onshore wind 23% of the time. This is means that we expect 29 days with waves in a typical November, of which 22 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.
