Barra do Sahy Swell Statistics, August: Surf with Light or Offshore Winds

This image shows only the swells directed at Barra do Sahy 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 show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow represent increasing swell sizes and red illustrates the biggest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the dominant swell direction, shown by the biggest spokes, was SSE, whereas the the prevailing wind blows from the E. 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 37% of the time, equivalent to 11 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal August but 8% of the time we expect swell in the range 2-3m (6.5-10ft) 8%, equivalent to (2 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Barra do Sahy is exposed to open water swells, we estimate that clean surf can be found at Barra do Sahy about 37% of the time and that surf is blown out by onshore wind 31% of the time. This is means that we expect 21 days with waves in a typical August, of which 11 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.
