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

This image shows only the swells directed at Lacerations (Nusa Lembongan) that coincided with light winds or offshore conditions over a normal southern hemisphere autumn and is based upon 8052 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 show increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the dominant swell direction, shown by the largest spokes, was SSW, whereas the the most common 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 22% of the time, equivalent to 20 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal southern hemisphere autumn but 22% of the time we expect swell in the range 2-3m (6.5-10ft) 22%, equivalent to (20 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Lacerations (Nusa Lembongan) is quite sheltered from open water swells, we calculate that clean surf can be found at Lacerations (Nusa Lembongan) about 22% of the time and that surf is spoilt by onshore wind 6% of the time. This is means that we expect 25 days with waves in a typical southern hemisphere autumn, of which 20 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.
