Centinela Swell Statistics, April: Surf with Light or Offshore Winds

This image shows only the swells directed at Centinela that coincided with light winds or offshore conditions through a typical April. It is based on 1680 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 illustrate increasing swell sizes and red represents biggest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the most common swell direction, shown by the longest spokes, was SW, whereas the the prevailing wind blows from the S. 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 7% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal April. Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Centinela is exposed to open water swells, we calculate that clean surf can be found at Centinela about 7% of the time and that surf is spoilt by onshore wind 93% of the time. This is means that we expect 30 days with waves in a typical April, of which 2 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.
