Estadísticas de Olas para Anse de Vauville, abril: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Anse de Vauville that coincided with light winds or offshore conditions through a typical April. It is based on 2157 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow illustrate increasing swell sizes and red represents highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell happens.
The diagram indicates that the most common swell direction, shown by the longest spokes, was W, whereas the the dominant wind blows from the NNW. 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 5% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal April. Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Anse de Vauville is exposed to open water swells, we calculate that clean surf can be found at Anse de Vauville about 5% of the time and that surf is blown out by onshore wind 16% of the time. This is means that we expect 6 days with waves in a typical April, of which 2 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.
