Windansea Swell Statistics, Summer: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Windansea that coincided with light winds or offshore conditions through a typical northern hemisphere summer and is based upon 8738 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 represent increasing swell sizes and red represents largest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the largest spokes, was SSW, whereas the the most common wind blows from the W. 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 46% of the time, equivalent to 42 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere summer but 3% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 3%, equivalent to (3 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Windansea is exposed to open water swells, we calculate that clean surf can be found at Windansea about 46% of the time and that surf is messed up by onshore wind 52% of the time. This is means that we expect 89 days with waves in a typical northern hemisphere summer, of which 42 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.
