Ujung Genteng Harbour Swell Statistics, Summer: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Ujung Genteng Harbour that coincided with light winds or offshore conditions through a typical southern hemisphere summer. It is based on 8485 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow illustrate increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the most common swell direction, shown by the biggest spokes, was SSW, whereas the the dominant wind blows from the WNW. 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 38% of the time, equivalent to 35 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal southern hemisphere summer but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (3 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Ujung Genteng Harbour is exposed to open water swells, we think that that clean surf can be found at Ujung Genteng Harbour about 38% of the time and that surf is blown out by onshore wind 62% of the time. This is means that we expect 91 days with waves in a typical southern hemisphere summer, of which 35 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.
