Sans Sousi Surf Stats

This chart shows the variation of swells directed at Sans Sousi through a typical February and is based upon 3120 NWW3 model predictions since 2007 (values every 3 hours). The wave model does not forecast wind and surf right at the shore so we have chosen the optimum grid node based on what we know about Sans Sousi. In the case of Sans Sousi, the best grid node is 18 km away (11 miles). The rose diagram describes the distribution of swell sizes and swell direction, while the graph at the bottom shows the same thing but lacks direction information. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. These occurred only 13% of the time. Green and yellow show increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how frequently that size swell happens. The diagram suggests that the dominant swell direction, shown by the longest spokes, was ENE (which was the same as the prevailing wind direction). Because the wave model grid is offshore, sometimes a strong offshore wind blows largest waves away from Sans Sousi and away from the coast. We group these with the no surf category of the bar chart. To avoid confusion we don't show these in the rose diagram. Because wind determines whether or not waves are surfable at Sans Sousi, you can view an alternative image that shows only the swells that were expected to coincide with glassy or offshore wind conditions. Over an average February, swells large enough to cause good for surfing waves at Sans Sousi run for about 87% of the time.
