Cap Sim Swell Statistics, August: 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 August. It is based on 2480 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow represent increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the prevailing swell direction, shown by the largest spokes, was NNW, whereas the the most common 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 92% of the time, equivalent to 29 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal August but 23% of the time we expect swell in the range 2-3m (6.5-10ft) 23%, equivalent to (7 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Cap Sim is exposed to open water swells, we estimate that clean surf can be found at Cap Sim about 92% of the time and that surf is messed up by onshore wind 6% of the time. This is means that we expect 30 days with waves in a typical August, of which 29 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.
