Cannon Beach/TolovanaBeach Swell Statistics, May: 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 May. It is based on 2838 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 represent increasing swell sizes and biggest 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 most common swell direction, shown by the largest spokes, was WSW, whereas the the prevailing wind blows from the WNW. 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 22% of the time, equivalent to 7 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal May but 10% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 10%, equivalent to (3 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 think that that clean surf can be found at Cannon Beach/TolovanaBeach about 22% of the time and that surf is blown out by onshore wind 49% of the time. This is means that we expect 22 days with waves in a typical May, of which 7 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.
