La Roche Percee (Bonhomme de Bourail) Surf Stats

All swells

(any wind direction)

Good Surf

(light / offshore wind)

This image illustrates the variation of swells directed at La Roche Percee (Bonhomme de Bourail) through a typical March, based on 3460 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 optimum grid node based on what we know about La Roche Percee (Bonhomme de Bourail). In the case of La Roche Percee (Bonhomme de Bourail), the best grid node is 44 km away (27 miles). The rose diagram describes the distribution of swell sizes and swell direction, while the graph at the bottom shows the same thing but 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 16% of the time. Green and yellow represent increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell happens. The diagram implies that the dominant swell direction, shown by the longest spokes, was S, whereas the the most common wind blows from the ESE. Because the wave model grid is offshore, sometimes a strong offshore wind blows largest waves away from La Roche Percee (Bonhomme de Bourail) and away from the coast. 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 clean enough to surf at La Roche Percee (Bonhomme de Bourail), you can select a similar diagram that shows only the swells that were expected to coincide with glassy or offshore wind conditions. Over an average March, swells large enough to cause surfable waves at La Roche Percee (Bonhomme de Bourail) run for about 59% of the time.
