Usal Beach Swell Statistics, November: 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 November and is based upon 2841 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 illustrate increasing swell sizes and red represents largest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the dominant swell direction, shown by the biggest spokes, was WNW, whereas the the most common wind blows from the NNW. 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 water swells exceeding >3m (>10ft) only occur 4% of the time in a typical November, equivalent to just one day but 18% of the time we expect swell in the range 2-3m (6.5-10ft) 18%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with expected offshore winds we calculate that clean surf can be found at Usal Beach about 32% of the time and that surf is spoilt by onshore wind 66% of the time. This is means that we expect 29 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.
