Usal Beach Swell Statistics, All Year: Surf with Light or Offshore Winds

This image shows only the swells directed at Usal Beach that coincided with light winds or offshore conditions through a typical year and is based upon 34628 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow show increasing swell sizes and red represents the biggest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was WNW, whereas the the prevailing wind blows from the NW. 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 21% of the time, equivalent to 77 days. Expect open water swells to exceed >3m (>10ft) 2% of the time (7 days). Taking into account the fraction of these swells that coincided with predicted offshore winds we think that that clean surf can be found at Usal Beach about 21% of the time and that surf is messed up by onshore wind 72% of the time. This is means that we expect 339 days with waves in a typical year, of which 77 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.
