Lacerations (Nusa Lembongan) Swell Statistics, September: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Lacerations (Nusa Lembongan) that coincided with light winds or offshore conditions over a normal September and is based upon 2880 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 red represents the highest swells, greater than >3m (>10ft). In each graph, 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 dominant 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 56% of the time, equivalent to 17 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal September but 55% of the time we expect swell in the range 2-3m (6.5-10ft) 55%, equivalent to (16 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Lacerations (Nusa Lembongan) is quite sheltered from open water swells, we estimate that clean surf can be found at Lacerations (Nusa Lembongan) about 56% of the time and that surf is spoilt by onshore wind 4% of the time. This is means that we expect 18 days with waves in a typical September, of which 17 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.
