Whitsand Bay and Tregantle Swell Statistics, May: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Whitsand Bay and Tregantle that coincided with light winds or offshore conditions through a typical May. It is based on 2696 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 represent increasing swell sizes and highest 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 longest spokes, was WSW, whereas the the dominant 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 18% of the time, equivalent to 6 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal May. Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Whitsand Bay and Tregantle is exposed to open water swells, we estimate that clean surf can be found at Whitsand Bay and Tregantle about 18% of the time and that surf is spoilt by onshore wind 53% of the time. This is means that we expect 22 days with waves in a typical May, of which 6 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.
