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

This image shows only the swells directed at Avalanche that coincided with light winds or offshore conditions over a normal December. It is based on 2705 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 represent increasing swell sizes and red illustrates the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the dominant swell direction, shown by the longest spokes, was NNW, whereas the the prevailing wind blows from the E. 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 56% of the time, equivalent to 17 days. Open water swells exceeding >3m (>10ft) only arise 3% of the time in a typical December, 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 expected offshore winds, and given the fact that Avalanche is exposed to open water swells, we calculate that clean surf can be found at Avalanche about 56% of the time and that surf is spoilt by onshore wind 21% of the time. This is means that we expect 23 days with waves in a typical December, of which 17 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.
