Jan Juc Swell Statistics, Spring: Surf with Light or Offshore Winds

This image shows only the swells directed at Jan Juc that coincided with light winds or offshore conditions through a typical southern hemisphere spring. It is based on 8476 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 represent increasing swell sizes and red illustrates largest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the most common swell direction, shown by the longest spokes, was WSW (which was the same as the most common 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 38% of the time, equivalent to 35 days. Open water swells exceeding >3m (>10ft) only happen 1.0% of the time in a typical southern hemisphere spring, equivalent to just one day but 4% of the time we expect swell in the range 2-3m (6.5-10ft) 4%, equivalent to (4 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Jan Juc is exposed to open water swells, we think that that clean surf can be found at Jan Juc about 38% of the time and that surf is spoilt by onshore wind 57% of the time. This is means that we expect 86 days with waves in a typical southern hemisphere spring, of which 35 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.
