Elliot Bay Swell Statistics, November: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Elliot Bay that coincided with light winds or offshore conditions over a normal November and is based upon 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 represent increasing swell sizes and red represents the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the prevailing swell direction, shown by the largest spokes, was ENE, whereas the the dominant wind blows from the WSW. 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 32% of the time, equivalent to 10 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal November. Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Elliot Bay is exposed to open water swells, we think that that clean surf can be found at Elliot Bay about 32% of the time and that surf is spoilt by onshore wind 35% of the time. This is means that we expect 20 days with waves in a typical November, of which 10 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.
