La Lette Blanche (Vieille Saint Girons) Surf Stats

This image shows the variation of swells directed at La Lette Blanche (Vieille Saint Girons) through a typical November, based on 3347 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast surf and wind right at the coast so we have chosen the most applicable grid node based on what we know about La Lette Blanche (Vieille Saint Girons). In the case of La Lette Blanche (Vieille Saint Girons), the best grid node is 15 km away (9 miles). The rose diagram shows the distribution of swell sizes and directions, while the graph at the bottom shows the same thing but without direction information. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. These occurred only 5% of the time. Green and yellow show increasing swell sizes and red illustrates the biggest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell was forecast. The diagram implies that the prevailing swell direction, shown by the biggest spokes, was WNW, whereas the the prevailing wind blows from the SSW. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from La Lette Blanche (Vieille Saint Girons) and out to sea. We combine these with the no surf category of the bar chart. To simplify things we don't show these in the rose plot. Because wind determines whether or not waves are surfable at La Lette Blanche (Vieille Saint Girons), you can view an alternative image that shows only the swells that were forecast to coincide with glassy or offshore wind conditions. Over an average November, swells large enough to cause good for surfing waves at La Lette Blanche (Vieille Saint Girons) run for about 95% of the time.
