Ampang Swell Statistics, All Year: Surf with Light or Offshore Winds

This image shows only the swells directed at Ampang that coincided with light winds or offshore conditions through a typical year. It is based on 28044 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 illustrate increasing swell sizes and red represents biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the most common swell direction, shown by the largest spokes, was SSW, whereas the the prevailing wind blows from the SSE. 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 21% of the time, equivalent to 77 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal year but 4% of the time we expect swell in the range 2-3m (6.5-10ft) 4%, equivalent to (15 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Ampang is slightly protected from open water swells, we think that that clean surf can be found at Ampang about 21% of the time and that surf is spoilt by onshore wind 39% of the time. This is means that we expect 219 days with waves in a typical year, of which 77 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.
