Anglet - Marinella Golf Statistieken, Hele Jaar: Golven met Licht of Offshore Winden
This image shows only the swells directed at Anglet - Marinella that coincided with light winds or offshore conditions over a normal year. It is based on 28042 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 shows highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell occurs.
The diagram indicates that the dominant swell direction, shown by the biggest spokes, was WNW (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 32% of the time, equivalent to 117 days. Open water swells exceeding >3m (>10ft) only happen 0.3% of the time in a typical year, equivalent to just one day but 4% of the time we expect swell in the range 2-3m (6.5-10ft) 4%, equivalent to (15 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Anglet - Marinella is exposed to open water swells, we think that that clean surf can be found at Anglet - Marinella about 32% of the time and that surf is blown out by onshore wind 59% of the time. This is means that we expect 332 days with waves in a typical year, of which 117 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.
