Avalanche Swell Statistics, February: 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 and is based upon 2440 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 illustrate increasing swell sizes and largest 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 dominant swell direction, shown by the biggest spokes, was NW, whereas the the most common 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 55% of the time, equivalent to 15 days. Open water swells exceeding >3m (>10ft) only arise 3% of the time in a typical February, equivalent to just one day but 28% of the time we expect swell in the range 2-3m (6.5-10ft) 28%, equivalent to (8 days). Taking into account the ratio of these swells that coincided with forecast 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 55% of the time and that surf is blown out by onshore wind 32% of the time. This is means that we expect 24 days with waves in a typical February, 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.
