Santa Clara Rivermouth Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at Santa Clara Rivermouth that coincided with light winds or offshore conditions through a typical October. It is based on 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 shows the biggest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the dominant swell direction, shown by the longest spokes, was WSW, whereas the the prevailing wind blows from the W. 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 4% of the time, equivalent to 1 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 Santa Clara Rivermouth is slightly protected from open water swells, we calculate that clean surf can be found at Santa Clara Rivermouth about 4% of the time and that surf is spoilt by onshore wind 12% of the time. This is means that we expect 5 days with waves in a typical October, of which 1 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.
