Ile de Re - Les Grenettes Swell Statistics, All Year: All Swell – Any Wind

The graph illustrates the range of swells directed at Ile de Re - Les Grenettes over a normal year and is based upon 34628 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind or surf right at the coast so we have chosen the optimum grid node based on what we know about Ile de Re - Les Grenettes. In this particular case the best grid node is 21 km away (13 miles).

The rose diagram describes the distribution of swell directions and swell sizes, while the graph at the bottom shows the same thing but lacks 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 happened only 11% of the time. Green and yellow show increasing swell sizes and red illustrates largest swells greater than >3m (>10ft). In each 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 longest spokes, was W, whereas the the most common wind blows from the NW. Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from Ile de Re - Les Grenettes and offshore. We group these with the no surf category of the bar chart. To avoid confusion we don't show these in the rose diagram. Because wind determines whether or not waves are good for surfing at Ile de Re - Les Grenettes, you can load a different image that shows only the swells that were predicted to coincide with glassy or offshore wind conditions. During a typical year, swells large enough to cause clean enough to surf waves at Ile de Re - Les Grenettes run for about 89% of the time.

IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
