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

This image shows only the swells directed at Avalanche that coincided with light winds or offshore conditions through a typical February. It is based on 2102 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 illustrates the biggest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the prevailing swell direction, shown by the longest spokes, was NW, whereas the the prevailing 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 57% of the time, equivalent to 16 days. Open water swells exceeding >3m (>10ft) only arise 3% of the time in a typical February, equivalent to just one day but 30% of the time we expect swell in the range 2-3m (6.5-10ft) 30%, equivalent to (8 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Avalanche is exposed to open water swells, we think that that clean surf can be found at Avalanche about 57% of the time and that surf is spoilt by onshore wind 29% of the time. This is means that we expect 24 days with waves in a typical February, of which 16 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.
