Statistiques de Houle pour Desperations, Mars: 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 March. It is based on 2716 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 illustrate increasing swell sizes and red represents biggest 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 SSW, whereas the the prevailing 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 37% of the time, equivalent to 11 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal March but 14% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 14%, equivalent to (4 days). Taking into account the ratio of these swells that coincided with forecast 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 37% of the time and that surf is messed up by onshore wind 53% of the time. This is means that we expect 28 days with waves in a typical March, of which 11 days should be clean enough to surf.

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.
