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

This image shows only the swells directed at 8th Street Jetty that coincided with light winds or offshore conditions through a typical May and is based upon 2696 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 the largest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was E, whereas the the most common wind blows from the SSW. 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 0.6% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal May. Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that 8th Street Jetty is slightly protected from open water swells, we calculate that clean surf can be found at 8th Street Jetty about 0.6% of the time and that surf is messed up by onshore wind 6% of the time. This is means that we expect 2 days with waves in a typical May, of which 0 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.
