Ampang Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at Ampang that coincided with light winds or offshore conditions over a normal southern hemisphere autumn and is based upon 8052 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 highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the prevailing swell direction, shown by the largest spokes, was SSW, whereas the the dominant wind blows from the SE. 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 25% of the time, equivalent to 23 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal southern hemisphere autumn but 4% of the time we expect swell in the range 2-3m (6.5-10ft) 4%, equivalent to (4 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Ampang is slightly protected from open water swells, we calculate that clean surf can be found at Ampang about 25% of the time and that surf is messed up by onshore wind 37% of the time. This is means that we expect 56 days with waves in a typical southern hemisphere autumn, of which 23 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.
