Manhattan Beach and Pier Swell Statistics, December: Surf with Light or Offshore Winds

This image shows only the swells directed at Manhattan Beach and Pier that coincided with light winds or offshore conditions over a normal December. It is based on 2953 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 highest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the largest spokes, was WSW, whereas the the dominant wind blows from the NNW. 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 41% of the time, equivalent to 12 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal December. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Manhattan Beach and Pier is exposed to open water swells, we calculate that clean surf can be found at Manhattan Beach and Pier about 41% of the time and that surf is blown out by onshore wind 43% of the time. This is means that we expect 25 days with waves in a typical December, of which 12 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.
