Anse Couleuvre Golf Statistieken, Hele Jaar: Golven met Licht of Offshore Winden
The rose diagram shows only the swells directed at Anse Couleuvre that coincided with light winds or offshore conditions over a normal year. It is based on 28044 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow represent increasing swell sizes and red illustrates the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs.
The diagram suggests that the most common swell direction, shown by the longest spokes, was NNE, whereas the the dominant wind blows from the E. The chart at the bottom shows the same thing but without direction information. For example, swells larger than 1.5 feet (0.5m) coincided with good wind conditions 12% of the time, equivalent to 44 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal year but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (11 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Anse Couleuvre is slightly protected from open water swells, we think that that clean surf can be found at Anse Couleuvre about 12% of the time and that surf is spoilt by onshore wind 7% of the time. This is means that we expect 69 days with waves in a typical year, of which 44 days should be surfable.
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.
