Jimmys Swell Statistics, All Year: Surf with Light or Offshore Winds

This image shows only the swells directed at Jimmys that coincided with light winds or offshore conditions over a normal year and is based upon 33220 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 show increasing swell sizes and red shows biggest swells greater than >3m (>10ft). In either graph, 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 largest spokes, was SSW, whereas the the prevailing wind blows from the SSE. 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 42% of the time, equivalent to 153 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal year but 7% of the time we expect swell in the range 2-3m (6.5-10ft) 7%, equivalent to (26 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Jimmys is exposed to open water swells, we estimate that clean surf can be found at Jimmys about 42% of the time and that surf is spoilt by onshore wind 58% of the time. This is means that we expect 365 days with waves in a typical year, of which 153 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.
