Statistiques de Surf de Dielette Left

This chart describes the combination of swells directed at Dielette Left over a normal June and is based upon 2784 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind and surf right at the coastline so we have chosen the optimum grid node based on what we know about Dielette Left, and at Dielette Left the best grid node is 12 km away (7 miles). The rose diagram shows the distribution of swell sizes and directions, while the graph at the bottom shows the same thing without direction information. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. These happened 65% of the time. Green and yellow represent increasing swell sizes and red shows the highest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell occurs. The diagram indicates that the prevailing swell direction, shown by the biggest spokes, was WNW (which was the same as the dominant wind direction). Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from Dielette Left and offshore. We group these with the no surf category of the bar chart. To simplify things we don't show these in the rose diagram. Because wind determines whether or not waves are good for surfing at Dielette Left, you can view an alternative image that shows only the swells that were predicted to coincide with glassy or offshore wind conditions. During a typical June, swells large enough to cause clean enough to surf waves at Dielette Left run for about 35% of the time.
