Zeneta Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at Zeneta that coincided with light winds or offshore conditions over a normal northern hemisphere autumn and is based upon 8724 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 represents the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the longest spokes, was NW, whereas the the dominant wind blows from the N. 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 34% of the time, equivalent to 31 days. Open water swells exceeding >3m (>10ft) only arise 1.4% of the time in a typical northern hemisphere autumn, equivalent to just one day but 8% of the time we expect swell in the range 2-3m (6.5-10ft) 8%, equivalent to (7 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Zeneta is exposed to open water swells, we calculate that clean surf can be found at Zeneta about 34% of the time and that surf is messed up by onshore wind 65% of the time. This is means that we expect 90 days with waves in a typical northern hemisphere autumn, of which 31 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.
