15th Street Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at 15th Street that coincided with light winds or offshore conditions over a normal October and is based upon 2976 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In each graph, 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 largest spokes, was SW, whereas the the most common 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 52% of the time, equivalent to 16 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 15th Street is exposed to open water swells, we think that that clean surf can be found at 15th Street about 52% of the time and that surf is blown out by onshore wind 45% of the time. This is means that we expect 30 days with waves in a typical October, of which 16 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.
