Estadísticas de Olas para Aberwystwyth Beach, Primavera: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Aberwystwyth Beach that coincided with light winds or offshore conditions through a typical northern hemisphere spring. It is based on 6577 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 illustrate increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how frequently that size swell happens.
The diagram suggests that the prevailing swell direction, shown by the longest spokes, was SW (which was the same as the dominant 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 1.4% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere spring. Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Aberwystwyth Beach is slightly protected from open water swells, we think that that clean surf can be found at Aberwystwyth Beach about 1.4% of the time and that surf is spoilt by onshore wind 16% of the time. This is means that we expect 15 days with waves in a typical northern hemisphere spring, of which 1 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.
