Estadísticas de Olas para Anglet - La Barre, Verano: Olas con Vientos Ligeros o Terrales
The rose diagram shows only the swells directed at Anglet - La Barre that coincided with light winds or offshore conditions over a normal northern hemisphere summer. It is based on 7265 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 show increasing swell sizes and red illustrates the largest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell was forecast.
The diagram indicates that the dominant swell direction, shown by the biggest spokes, was WNW, whereas the the most common 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 7% of the time, equivalent to 6 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal northern hemisphere summer but 6% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 6%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Anglet - La Barre is slightly protected from open water swells, we estimate that clean surf can be found at Anglet - La Barre about 7% of the time and that surf is messed up by onshore wind 21% of the time. This is means that we expect 25 days with waves in a typical northern hemisphere summer, of which 6 days should be clean enough to surf.
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.
