Statistiques de Houle pour Desperations, Été: Vagues avec Vents Légers ou Favorables.

The rose diagram shows only the swells directed at Desperations that coincided with light winds or offshore conditions through a typical southern hemisphere summer and is based upon 8485 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 represents the largest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the dominant swell direction, shown by the largest spokes, was SSW, whereas the the most common 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 29% of the time, equivalent to 26 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal southern hemisphere summer but 10% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 10%, equivalent to (9 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Desperations is exposed to open water swells, we estimate that clean surf can be found at Desperations about 29% of the time and that surf is spoilt by onshore wind 51% of the time. This is means that we expect 73 days with waves in a typical southern hemisphere summer, of which 26 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.
