Underwater Point Swell Statistics, August: Surf with Light or Offshore Winds

This image shows only the swells directed at Underwater Point that coincided with light winds or offshore conditions through a typical August. It is based on 2976 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 red illustrates highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the dominant swell direction, shown by the biggest spokes, was SW (which was the same as the dominant wind direction). 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 33% of the time, equivalent to 10 days. Expect open water swells to exceed >3m (>10ft) 9% of the time (3 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Underwater Point is exposed to open water swells, we calculate that clean surf can be found at Underwater Point about 33% of the time and that surf is messed up by onshore wind 56% of the time. This is means that we expect 28 days with waves in a typical August, 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.
