Barra do Sahy Swell Statistics, All Year: 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 year. It is based on 28044 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 biggest swells greater than >3m (>10ft). In each 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 largest 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 36% of the time, equivalent to 131 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal year but 5% of the time we expect swell in the range 2-3m (6.5-10ft) 5%, equivalent to (18 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Barra do Sahy is exposed to open water swells, we think that that clean surf can be found at Barra do Sahy about 36% of the time and that surf is messed up by onshore wind 31% of the time. This is means that we expect 245 days with waves in a typical year, of which 131 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.
