Statistiques de Surf de Morros dos Conventos

This chart shows the variation of swells directed at Morros dos Conventos through a typical November. It is based on 2867 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 Morros dos Conventos. In this particular case the best grid node is 38 km away (24 miles). The rose diagram describes the distribution of swell sizes and directions, while the graph at the bottom shows the same thing without direction information. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. These occurred only 58% of the time. Green and yellow represent increasing swell sizes and red represents the biggest 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 SSE, whereas the the prevailing wind blows from the E. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Morros dos Conventos and out to sea. We combine these with the no surf category of the bar chart. To simplify things we don't show these in the rose plot. Because wind determines whether or not waves are good for surfing at Morros dos Conventos, you can load a different image that shows only the swells that were expected to coincide with glassy or offshore wind conditions. Over an average November, swells large enough to cause clean enough to surf waves at Morros dos Conventos run for about 42% of the time.
