Jelly Babies Swell Statistics, Autumn: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Jelly Babies that coincided with light winds or offshore conditions over a normal southern hemisphere autumn. It is based on 8682 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 illustrate increasing swell sizes and red shows highest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the most common swell direction, shown by the biggest spokes, was SSW, whereas the the dominant 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 53% of the time, equivalent to 48 days. Expect open water swells to exceed >3m (>10ft) 1.7% of the time (2 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Jelly Babies is exposed to open water swells, we estimate that clean surf can be found at Jelly Babies about 53% of the time and that surf is messed up by onshore wind 46% of the time. This is means that we expect 90 days with waves in a typical southern hemisphere autumn, of which 48 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.
