Usal Beach Swell Statistics, March: 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 March. It is based on 2716 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 highest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the most common swell direction, shown by the biggest spokes, was WNW (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 18% of the time, equivalent to 6 days. Open water swells exceeding >3m (>10ft) only occur 3% of the time in a typical March, equivalent to just one day but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (3 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 18% of the time and that surf is messed up by onshore wind 80% of the time. This is means that we expect 30 days with waves in a typical March, of which 6 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.
