Alibaba Swell Statistics, Dezembro: Surf with Light or Offshore Winds

This image shows only the swells directed at Alibaba that coincided with light winds or offshore conditions through a typical December and is based upon 2953 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. 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 NNW, whereas the the most common wind blows from the NE. 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 22% of the time, equivalent to 7 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal December but 12% of the time we expect swell in the range 2-3m (6.5-10ft) 12%, equivalent to (4 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Alibaba is exposed to open water swells, we calculate that clean surf can be found at Alibaba about 22% of the time and that surf is spoilt by onshore wind 34% of the time. This is means that we expect 17 days with waves in a typical December, of which 7 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.
