Areia Preta Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at Areia Preta that coincided with light winds or offshore conditions through a typical southern hemisphere autumn. It is based on 8682 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 highest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the dominant swell direction, shown by the biggest spokes, was NE, whereas the the dominant wind blows from the ESE. 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 3% of the time, equivalent to 3 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal southern hemisphere autumn. Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Areia Preta is exposed to open water swells, we estimate that clean surf can be found at Areia Preta about 3% of the time and that surf is spoilt by onshore wind 87% of the time. This is means that we expect 82 days with waves in a typical southern hemisphere autumn, of which 3 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.
