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

This image shows only the swells directed at Ujung Siging that coincided with light winds or offshore conditions through a typical June. It is based on 2786 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow illustrate increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the dominant 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 44% of the time, equivalent to 13 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal June but 20% of the time we expect swell in the range 2-3m (6.5-10ft) 20%, equivalent to (6 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Ujung Siging is exposed to open water swells, we think that that clean surf can be found at Ujung Siging about 44% of the time and that surf is messed up by onshore wind 55% of the time. This is means that we expect 30 days with waves in a typical June, of which 13 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.
