South Jetty and Dog Beach Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at South Jetty and Dog Beach that coincided with light winds or offshore conditions over a normal 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 show increasing swell sizes and red shows the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was SW, whereas the the prevailing 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 56% of the time, equivalent to 17 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal October. Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that South Jetty and Dog Beach is exposed to open water swells, we estimate that clean surf can be found at South Jetty and Dog Beach about 56% of the time and that surf is messed up by onshore wind 41% of the time. This is means that we expect 30 days with waves in a typical October, of which 17 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.
