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

This image shows only the swells directed at Zeneta that coincided with light winds or offshore conditions through a typical December. It is based on 2705 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 biggest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the dominant swell direction, shown by the longest spokes, was NW, whereas the the prevailing wind blows from the ENE. 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 43% of the time, equivalent to 13 days. Open water swells exceeding >3m (>10ft) only occur 1.8% of the time in a typical December, equivalent to just one day but 15% of the time we expect swell in the range 2-3m (6.5-10ft) 15%, equivalent to (4 days). Taking into account the ratio 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 43% of the time and that surf is messed up by onshore wind 56% of the time. This is means that we expect 30 days with waves in a typical December, of which 13 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.
