Banzai Swell Statistics, January: Surf with Light or Offshore Winds

This image shows only the swells directed at Banzai that coincided with light winds or offshore conditions over a normal January and is based upon 2372 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 represent increasing swell sizes and red represents the largest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the dominant swell direction, shown by the largest spokes, was SE, whereas the the most common 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 8% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal January. Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Banzai is exposed to open water swells, we think that that clean surf can be found at Banzai about 8% of the time and that surf is messed up by onshore wind 43% of the time. This is means that we expect 16 days with waves in a typical January, of which 2 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.
