Estadísticas de Olas para Aberdaron, agosto: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Aberdaron that coincided with light winds or offshore conditions through a typical August and is based upon 2479 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 represent increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how frequently that size swell happens.
The diagram suggests that the most common swell direction, shown by the longest spokes, was WSW, whereas the the most common wind blows from the WSW. 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 0% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal August. Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Aberdaron is slightly protected from open water swells, we calculate that clean surf can be found at Aberdaron about 0% of the time and that surf is spoilt by onshore wind 13% of the time. This is means that we expect 4 days with waves in a typical August, of which 0 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.
