North Jetty at Eureka Swell Statistics, January: 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 January and is based upon 2620 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 biggest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the most common swell direction, shown by the biggest spokes, was WNW, whereas the the prevailing wind blows from the W. 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 50% of the time, equivalent to 16 days. Expect open water swells to exceed >3m (>10ft) 16% of the time (5 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that North Jetty at Eureka is exposed to open water swells, we estimate that clean surf can be found at North Jetty at Eureka about 50% of the time and that surf is messed up by onshore wind 46% of the time. This is means that we expect 30 days with waves in a typical January, of which 16 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.
