Cannon Beach/TolovanaBeach Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at Cannon Beach/TolovanaBeach that coincided with light winds or offshore conditions through a typical northern hemisphere autumn. It is based on 7252 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow show increasing swell sizes and red shows the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the longest spokes, was WSW, whereas the the most common wind blows from the SE. 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 28% of the time, equivalent to 25 days. Expect open water swells to exceed >3m (>10ft) 2% of the time (2 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Cannon Beach/TolovanaBeach is exposed to open water swells, we estimate that clean surf can be found at Cannon Beach/TolovanaBeach about 28% of the time and that surf is blown out by onshore wind 39% of the time. This is means that we expect 61 days with waves in a typical northern hemisphere autumn, of which 25 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.
