Estadísticas de Olas para Santa Maria - Anjos, Invierno: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Santa Maria - Anjos that coincided with light winds or offshore conditions through a typical northern hemisphere winter and is based upon 6931 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 red represents the highest 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 biggest spokes, was NW, whereas the the dominant wind blows from the SW. 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 25% of the time, equivalent to 23 days. Expect open water swells to exceed >3m (>10ft) 2% of the time (2 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Santa Maria - Anjos is exposed to open water swells, we think that that clean surf can be found at Santa Maria - Anjos about 25% of the time and that surf is blown out by onshore wind 57% of the time. This is means that we expect 75 days with waves in a typical northern hemisphere winter, of which 23 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.
