Zero Swell Statistics, Spring: Surf with Light or Offshore Winds

This image shows only the swells directed at Zero that coincided with light winds or offshore conditions over a normal northern hemisphere spring and is based upon 6580 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 highest swells greater than >3m (>10ft) are shown in red. In both graphs, 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 SSW, whereas the the dominant 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 40% of the time, equivalent to 36 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere spring but 5% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 5%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Zero is exposed to open water swells, we think that that clean surf can be found at Zero about 40% of the time and that surf is blown out by onshore wind 43% of the time. This is means that we expect 76 days with waves in a typical northern hemisphere spring, of which 36 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.
