Statistiques de Surf de Kilometerstein Vier Hornum (Sylt)

This chart shows the variation of swells directed at Kilometerstein Vier Hornum (Sylt) through a typical October and is based upon 3470 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind or surf right at the coast so we have chosen the most applicable grid node based on what we know about Kilometerstein Vier Hornum (Sylt), and at Kilometerstein Vier Hornum (Sylt) the best grid node is 33 km away (21 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 illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. These happened only 57% of the time. Green and yellow illustrate increasing swell sizes and red shows the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell was forecast. The diagram indicates that the dominant swell direction, shown by the biggest spokes, was WNW, whereas the the prevailing wind blows from the SW. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Kilometerstein Vier Hornum (Sylt) and out to sea. We group these with the no surf category of the bar chart. To keep it simple we don't show these in the rose plot. Because wind determines whether or not waves are surfable at Kilometerstein Vier Hornum (Sylt), you can load a different image that shows only the swells that were forecast to coincide with glassy or offshore wind conditions. Over an average October, swells large enough to cause good for surfing waves at Kilometerstein Vier Hornum (Sylt) run for about 43% of the time.
