17th Ave Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at 17th Ave that coincided with light winds or offshore conditions through a typical October. It is based on 2975 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 both graphs, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the dominant swell direction, shown by the largest spokes, was SE, whereas the the most common wind blows from the ENE. 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 13% of the time, equivalent to 4 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal October. Taking into account the proportion of these swells that coincided with forecast offshore winds we calculate that clean surf can be found at 17th Ave about 13% of the time and that surf is spoilt by onshore wind 28% of the time. This is means that we expect 13 days with waves in a typical October, of which 4 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.
