Statistiques de Houle pour Aln Estuary, Mai: Vagues avec Vents Légers ou Favorables.

The rose diagram shows only the swells directed at Aln Estuary that coincided with light winds or offshore conditions over a normal May. It is based on 2200 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 show increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the biggest spokes, was NNE, whereas the the most common wind blows from the SW. 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 4% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal May. Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Aln Estuary is slightly protected from open water swells, we estimate that clean surf can be found at Aln Estuary about 4% of the time and that surf is messed up by onshore wind 11% of the time. This is means that we expect 5 days with waves in a typical May, of which 1 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.
