8th Street Jetty Swell Statistics, October: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at 8th Street Jetty that coincided with light winds or offshore conditions through a typical October. 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 illustrate increasing swell sizes and red represents highest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the dominant swell direction, shown by the longest spokes, was ENE, whereas the the dominant wind blows from the WNW. 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 3% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal October. Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that 8th Street Jetty is slightly protected from open water swells, we think that that clean surf can be found at 8th Street Jetty about 3% of the time and that surf is messed up by onshore wind 11% of the time. This is means that we expect 4 days with waves in a typical October, of which 1 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.
