Shimoda Yamatoken (Tatado Hama) Surf Stats

The graph illustrates the combination of swells directed at Shimoda Yamatoken (Tatado Hama) through a typical July, based on 3472 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind or surf right at the coastline so we have chosen the best grid node based on what we know about Shimoda Yamatoken (Tatado Hama). In this particular case the best grid node is 19 km away (12 miles). The rose diagram shows the distribution of swell directions and swell sizes, while the graph at the bottom shows the same thing without 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 72% of the time. Green and yellow illustrate increasing swell sizes and red shows largest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell happens. The diagram indicates that the dominant swell direction, shown by the longest spokes, was SE, whereas the the most common 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 Shimoda Yamatoken (Tatado Hama) and out to sea. 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 plot. Because wind determines whether or not waves are surfable at Shimoda Yamatoken (Tatado Hama), 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 July, swells large enough to cause good for surfing waves at Shimoda Yamatoken (Tatado Hama) run for about 28% of the time.
