Agate Beach Swell Statistics, November: Surf with Light or Offshore Winds
This image shows only the swells directed at Agate Beach that coincided with light winds or offshore conditions through a typical November. It is based on 2387 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 illustrate 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 happens.
The diagram indicates that the most common swell direction, shown by the largest spokes, was W, whereas the the most common wind blows from the S. 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 30% of the time, equivalent to 9 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (2 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Agate Beach is exposed to open water swells, we think that that clean surf can be found at Agate Beach about 30% of the time and that surf is blown out by onshore wind 68% of the time. This is means that we expect 29 days with waves in a typical November, of which 9 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.
