Nordseeklinik Westerland (Sylt) Surf Stats

This chart shows the range of swells directed at Nordseeklinik Westerland (Sylt) through an average October, based on 2975 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast surf and wind right at the shore so we have chosen the most applicable grid node based on what we know about Nordseeklinik Westerland (Sylt), and at Nordseeklinik Westerland (Sylt) the best grid node is 21 km away (13 miles). The rose diagram illustrates the distribution of swell directions and swell sizes, 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 happened only 37% of the time. Green and yellow represent increasing swell sizes and red illustrates biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell was forecast. The diagram suggests that the most common swell direction, shown by the longest spokes, was W, whereas the the prevailing wind blows from the SW. Because the wave model grid is offshore, sometimes a strong offshore wind blows largest waves away from Nordseeklinik Westerland (Sylt) and away from the coast. We lump these in with the no surf category of the bar chart. To keep it simple we don't show these in the rose diagram. Because wind determines whether or not waves are good for surfing at Nordseeklinik Westerland (Sylt), you can load a different image that shows only the swells that were forecast to coincide with glassy or offshore wind conditions. In a typical October, swells large enough to cause clean enough to surf waves at Nordseeklinik Westerland (Sylt) run for about 63% of the time.
