Lighthouse Reef Swell Statistics, March: Surf with Light or Offshore Winds

This image shows only the swells directed at Lighthouse Reef that coincided with light winds or offshore conditions through a typical March. It is based on 2716 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 commonly that size swell was forecast.

The diagram implies that the dominant swell direction, shown by the largest spokes, was E, whereas the the prevailing wind blows from the NE. 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 14% of the time, equivalent to 4 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal March. Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Lighthouse Reef is exposed to open water swells, we estimate that clean surf can be found at Lighthouse Reef about 14% of the time and that surf is messed up by onshore wind 22% of the time. This is means that we expect 11 days with waves in a typical March, of which 4 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.
