Aligator Rock Swell Statistics, November: Surf with Light or Offshore Winds

This image shows only the swells directed at Aligator Rock that coincided with light winds or offshore conditions through a typical 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 show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and red shows biggest 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 dominant swell direction, shown by the largest spokes, was NNW, whereas the the prevailing wind blows from the E. 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 54% of the time, equivalent to 16 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (2 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Aligator Rock is exposed to open water swells, we estimate that clean surf can be found at Aligator Rock about 54% of the time and that surf is messed up by onshore wind 5% of the time. This is means that we expect 18 days with waves in a typical November, of which 16 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.
