Statistiques de Surf de Praia da Foz Cabo Espichel Sesimbra

This chart describes the variation of swells directed at Praia da Foz Cabo Espichel Sesimbra through a typical October, based on 3471 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 Praia da Foz Cabo Espichel Sesimbra. In the case of Praia da Foz Cabo Espichel Sesimbra, the best grid node is 27 km away (17 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 represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. These occurred only 7% of the time. Green and yellow represent increasing swell sizes and red illustrates the highest swells, greater than >3m (>10ft). In each graph, 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 largest spokes, was WNW, whereas the the dominant wind blows from the NNW. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Praia da Foz Cabo Espichel Sesimbra and out to sea. We combine these 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 surfable at Praia da Foz Cabo Espichel Sesimbra, you can view an alternative image that shows only the swells that were expected to coincide with glassy or offshore wind conditions.
