Avalanche Swell Statistics, Ottobre: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Avalanche that coincided with light winds or offshore conditions over a normal October. It is based on 2976 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 red shows highest swells greater than >3m (>10ft). In either graph, 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 NNW, 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 47% of the time, equivalent to 15 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal October but 11% of the time we expect swell in the range 2-3m (6.5-10ft) 11%, equivalent to (3 days). Taking into account the proportion 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 47% of the time and that surf is spoilt by onshore wind 14% of the time. This is means that we expect 19 days with waves in a typical October, of which 15 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.
