Estadísticas de Olas para Barra do Ribeira, Otoño: Olas con Vientos Ligeros o Terrales

The rose diagram shows only the swells directed at Barra do Ribeira that coincided with light winds or offshore conditions through a typical southern hemisphere autumn. It is based on 6580 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 biggest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was SE (which was the same as the prevailing 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 37% of the time, equivalent to 34 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal southern hemisphere autumn but 7% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 7%, equivalent to (6 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Barra do Ribeira is exposed to open water swells, we estimate that clean surf can be found at Barra do Ribeira about 37% of the time and that surf is blown out by onshore wind 63% of the time. This is means that we expect 91 days with waves in a typical southern hemisphere autumn, of which 34 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.
