Banzai Pipeline and Backdoor Swell Statistics, Settembre: 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 through a typical September. It is based on 2400 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 illustrates highest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the most common swell direction, shown by the longest 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 35% of the time, equivalent to 10 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal September but 12% of the time we expect swell in the range 2-3m (6.5-10ft) 12%, equivalent to (4 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Banzai Pipeline and Backdoor is exposed to open water swells, we calculate that clean surf can be found at Banzai Pipeline and Backdoor about 35% of the time and that surf is messed up by onshore wind 1.0% of the time. This is means that we expect 11 days with waves in a typical September, of which 10 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.
