Padang Padang Swell Statistics, Winter: Surf with Light or Offshore Winds
This image shows only the swells directed at Padang Padang that coincided with light winds or offshore conditions through a typical southern hemisphere winter. It is based on 6538 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 biggest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how often that size swell happens.
The diagram indicates that the prevailing swell direction, shown by the biggest spokes, was SSW, whereas the the prevailing wind blows from the ESE. 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 98% of the time, equivalent to 89 days. Expect open water swells to exceed >3m (>10ft) 1.7% of the time (2 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Padang Padang is slightly protected from open water swells, we think that that clean surf can be found at Padang Padang about 98% of the time and that surf is blown out by onshore wind 1.0% of the time. This is means that we expect 90 days with waves in a typical southern hemisphere winter, of which 89 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.
