Statistiques de Houle pour Abermawr, Toute l'Année: Vagues avec Vents Légers ou Favorables.
This image shows only the swells directed at Abermawr that coincided with light winds or offshore conditions through a typical year and is based upon 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 illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell was forecast.
The diagram implies that the dominant swell direction, shown by the longest spokes, was SW (which was the same as the most common 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 10% of the time, equivalent to 36 days. Expect open water swells to exceed >3m (>10ft) 0.5% of the time (2 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Abermawr is slightly protected from open water swells, we think that that clean surf can be found at Abermawr about 10% of the time and that surf is blown out by onshore wind 30% of the time. This is means that we expect 146 days with waves in a typical year, of which 36 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.
