La Boya Swell Statistics, Spring: Surf with Light or Offshore Winds

This image shows only the swells directed at La Boya that coincided with light winds or offshore conditions through a typical southern hemisphere spring and is based upon 8724 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 biggest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the dominant swell direction, shown by the biggest spokes, was SSE, whereas the the prevailing wind blows from the E. 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 16% of the time, equivalent to 15 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal southern hemisphere spring. Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that La Boya is exposed to open water swells, we calculate that clean surf can be found at La Boya about 16% of the time and that surf is messed up by onshore wind 34% of the time. This is means that we expect 46 days with waves in a typical southern hemisphere spring, of which 15 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.
