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

The rose diagram shows only the swells directed at Jackals that coincided with light winds or offshore conditions through a typical January and is based upon 2372 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 illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the most common swell direction, shown by the biggest spokes, was SSW (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 73% of the time, equivalent to 23 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal January but 15% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 15%, equivalent to (5 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Jackals is exposed to open water swells, we estimate that clean surf can be found at Jackals about 73% of the time and that surf is blown out by onshore wind 27% of the time. This is means that we expect 31 days with waves in a typical January, of which 23 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.
