Banzai Pipeline and Backdoor Swell Statistics, Autumn: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Banzai Pipeline and Backdoor that coincided with light winds or offshore conditions over a normal northern hemisphere autumn. It is based on 7252 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In each 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 NNW, whereas the the dominant wind blows from the E. 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 45% of the time, equivalent to 41 days. Expect open water swells to exceed >3m (>10ft) 6% of the time (5 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Banzai Pipeline and Backdoor is exposed to open water swells, we think that that clean surf can be found at Banzai Pipeline and Backdoor about 45% of the time and that surf is spoilt by onshore wind 14% of the time. This is means that we expect 54 days with waves in a typical northern hemisphere autumn, of which 41 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.
