Statistiques de Houle pour Avalanche, Avril: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Avalanche that coincided with light winds or offshore conditions over a normal April and is based upon 2160 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow show increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In each graph, 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 largest spokes, was NW, whereas the the dominant wind blows from the ENE. 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 44% of the time, equivalent to 13 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal April but 14% of the time we expect swell in the range 2-3m (6.5-10ft) 14%, equivalent to (4 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Avalanche is exposed to open water swells, we estimate that clean surf can be found at Avalanche about 44% of the time and that surf is spoilt by onshore wind 14% of the time. This is means that we expect 17 days with waves in a typical April, of which 13 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.
