Ujung Siging Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at Ujung Siging that coincided with light winds or offshore conditions over a normal southern hemisphere winter 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 show increasing swell sizes and red represents largest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the most common swell direction, shown by the largest spokes, was SSW, whereas the the most common 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 32% of the time, equivalent to 29 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal southern hemisphere winter but 15% of the time we expect swell in the range 2-3m (6.5-10ft) 15%, equivalent to (14 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Ujung Siging is exposed to open water swells, we estimate that clean surf can be found at Ujung Siging about 32% of the time and that surf is blown out by onshore wind 67% of the time. This is means that we expect 90 days with waves in a typical southern hemisphere winter, of which 29 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.
