Anse Trabaud Swell Statistics, Giugno: Surf with Light or Offshore Winds
The rose diagram shows only the swells directed at Anse Trabaud that coincided with light winds or offshore conditions through a typical June. It is based on 2306 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 shows the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell occurs.
The diagram indicates that the prevailing swell direction, shown by the largest spokes, was E (which was the same as the most common wind direction). 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 0% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal June. Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Anse Trabaud is slightly protected from open water swells, we calculate that clean surf can be found at Anse Trabaud about 0% of the time and that surf is spoilt by onshore wind 69% of the time. This is means that we expect 21 days with waves in a typical June, of which 0 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.
