Good Surf

(light / offshore wind)

This picture describes the range of swells directed at Imposivel over a normal February, based on 3120 NWW3 model predictions since 2007 (values every 3 hours). The wave model does not forecast surf and wind right at the coast so we have chosen the best grid node based on what we know about Imposivel. In the case of Imposivel, the best grid node is 43 km away (27 miles). The rose diagram describes 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 0.2% of the time. Green and yellow represent increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell was forecast. The diagram implies that the prevailing swell direction, shown by the largest spokes, was SE, whereas the the dominant 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 Imposivel and out to sea. We lump these in with the no surf category of the bar chart. To avoid confusion we don't show these in the rose graph. Because wind determines whether or not waves are good for surfing at Imposivel, you can select a similar diagram that shows only the swells that were predicted to coincide with glassy or offshore wind conditions. During a typical February, swells large enough to cause clean enough to surf waves at Imposivel run for about 100% of the time.
