Cannon Beach Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at Cannon Beach that coincided with light winds or offshore conditions over a normal 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 show 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 often that size swell occurs.

The diagram indicates that the dominant swell direction, shown by the biggest spokes, was SW, whereas the the most common wind blows from the ESE. 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 48% of the time, equivalent to 15 days. Open water swells exceeding >3m (>10ft) only happen 3% of the time in a typical October, equivalent to just one day but 16% of the time we expect swell in the range 2-3m (6.5-10ft) 16%, equivalent to (5 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Cannon Beach is exposed to open water swells, we think that that clean surf can be found at Cannon Beach about 48% of the time and that surf is messed up by onshore wind 28% of the time. This is means that we expect 24 days with waves in a typical October, of which 15 days should be clean enough to surf.

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.
