Axim Swell Statistics, All Year: Surf with Light or Offshore Winds
This image shows only the swells directed at Axim that coincided with light winds or offshore conditions through a typical year. It is based on 28044 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 highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell happens.
The diagram indicates that the prevailing swell direction, shown by the biggest spokes, was SSW (which was the same as the dominant wind direction). 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 7% of the time, equivalent to 26 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal year but 3% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 3%, equivalent to (11 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Axim is exposed to open water swells, we calculate that clean surf can be found at Axim about 7% of the time and that surf is blown out by onshore wind 89% of the time. This is means that we expect 350 days with waves in a typical year, of which 26 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.
