Jailbreaks Swell Statistics, July: Surf with Light or Offshore Winds

This image shows only the swells directed at Jailbreaks that coincided with light winds or offshore conditions through a typical July and is based upon 2976 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 represents the largest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the prevailing swell direction, shown by the largest spokes, was S, whereas the the most common wind blows from the W. 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 43% of the time, equivalent to 13 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal July but 27% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 27%, equivalent to (8 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Jailbreaks is exposed to open water swells, we calculate that clean surf can be found at Jailbreaks about 43% of the time and that surf is blown out by onshore wind 43% of the time. This is means that we expect 27 days with waves in a typical July, of which 13 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.
