China Walls Swell Statistics, Summer: Surf with Light or Offshore Winds

This image shows only the swells directed at China Walls that coincided with light winds or offshore conditions through a typical northern hemisphere summer and is based upon 8738 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 represent increasing swell sizes and red represents the highest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the dominant swell direction, shown by the longest spokes, was S, whereas the the dominant 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 68% of the time, equivalent to 62 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere summer but 28% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 28%, equivalent to (25 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that China Walls is exposed to open water swells, we calculate that clean surf can be found at China Walls about 68% of the time and that surf is spoilt by onshore wind 5% of the time. This is means that we expect 66 days with waves in a typical northern hemisphere summer, of which 62 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.
