North Jetty at Eureka Swell Statistics, October: Surf with Light or Offshore Winds

This image shows only the swells directed at North Jetty at Eureka that coincided with light winds or offshore conditions through a typical October. It is based on 2480 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. 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 frequently that size swell was forecast.

The diagram suggests that the prevailing swell direction, shown by the longest spokes, was WNW, whereas the the most common wind blows from the NW. 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 9 days. Open water swells exceeding >3m (>10ft) only occur 4% of the time in a typical October, equivalent to just one day but 14% of the time we expect swell in the range 2-3m (6.5-10ft) 14%, equivalent to (4 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that North Jetty at Eureka is exposed to open water swells, we think that that clean surf can be found at North Jetty at Eureka about 28% of the time and that surf is messed up by onshore wind 64% of the time. This is means that we expect 29 days with waves in a typical October, of which 9 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.
