Estadísticas de Olas para Anse a La Gourde, diciembre: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Anse a La Gourde that coincided with light winds or offshore conditions through a typical December. It is based on 2457 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 show increasing swell sizes and red represents largest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs.
The diagram suggests that the prevailing swell direction, shown by the biggest spokes, was NE, whereas the the most common wind blows from the ENE. 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 happen in a normal December. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Anse a La Gourde is exposed to open water swells, we calculate that clean surf can be found at Anse a La Gourde about 5% of the time and that surf is blown out by onshore wind 93% of the time. This is means that we expect 29 days with waves in a typical December, 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.
