Zuma Beach Swell Statistics, December: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Zuma Beach that coincided with light winds or offshore conditions over a normal 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 show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and red shows the highest swells, greater than >3m (>10ft). 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 biggest spokes, was WSW, 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 60% of the time, equivalent to 18 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal December but 5% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 5%, equivalent to (2 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Zuma Beach is exposed to open water swells, we estimate that clean surf can be found at Zuma Beach about 60% of the time and that surf is spoilt by onshore wind 25% of the time. This is means that we expect 26 days with waves in a typical December, of which 18 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.
