Chadbourne Gulch Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at Chadbourne Gulch that coincided with light winds or offshore conditions through a typical 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 red represents the biggest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the most common swell direction, shown by the longest spokes, was W, whereas the the prevailing wind blows from the NW. 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 25% of the time, equivalent to 8 days. Open water swells exceeding >3m (>10ft) only occur 2% of the time in a typical October, equivalent to just one day but 10% of the time we expect swell in the range 2-3m (6.5-10ft) 10%, equivalent to (3 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Chadbourne Gulch is exposed to open water swells, we calculate that clean surf can be found at Chadbourne Gulch about 25% of the time and that surf is spoilt by onshore wind 55% of the time. This is means that we expect 25 days with waves in a typical October, of which 8 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.
