Statistiques de Houle pour Jackals, Printemps: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Jackals that coincided with light winds or offshore conditions through a typical northern hemisphere spring. It is based on 8052 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow show increasing swell sizes and red shows highest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the dominant swell direction, shown by the largest spokes, was SSW, whereas the the dominant wind blows from the WSW. 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 65% of the time, equivalent to 59 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere spring but 1.7% of the time we expect swell in the range 2-3m (6.5-10ft) 1.7%, equivalent to (2 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Jackals is exposed to open water swells, we think that that clean surf can be found at Jackals about 65% of the time and that surf is spoilt by onshore wind 35% of the time. This is means that we expect 91 days with waves in a typical northern hemisphere spring, of which 59 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.
