Statistiques de Surf de Papa Tangaroa

The graph illustrates the combination of swells directed at Papa Tangaroa through an average June. It is based on 3266 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast surf and wind right at the coastline so we have chosen the optimum grid node based on what we know about Papa Tangaroa, and at Papa Tangaroa the best grid node is 22 km away (14 miles). The rose diagram shows the distribution of swell sizes and directions, 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 occurred only 12% of the time. Green and yellow represent increasing swell sizes and red shows largest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens. The diagram implies that the most common swell direction, shown by the biggest spokes, was SSW, whereas the the most common wind blows from the E. Because the wave model grid is offshore, sometimes a strong offshore wind blows largest waves away from Papa Tangaroa and away from the coast. 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 surfable at Papa Tangaroa, you can select a similar diagram that shows only the swells that were predicted to coincide with glassy or offshore wind conditions. In a typical June, swells large enough to cause good for surfing waves at Papa Tangaroa run for about 88% of the time.
