Carbis Bay Swell Statistics, May: Surf with Light or Offshore Winds

This image shows only the swells directed at Carbis Bay that coincided with light winds or offshore conditions through a typical May and is based upon 2200 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 the largest 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 prevailing swell direction, shown by the largest spokes, was W, whereas the the most common wind blows from the WNW. 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 29% of the time, equivalent to 9 days. Open water swells exceeding >3m (>10ft) only happen 2% of the time in a typical May, equivalent to just one day but 14% of the time we expect swell in the range 2-3m (6.5-10ft) 14%, equivalent to (4 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Carbis Bay is slightly protected from open water swells, we calculate that clean surf can be found at Carbis Bay about 29% of the time and that surf is spoilt by onshore wind 19% of the time. This is means that we expect 15 days with waves in a typical May, of which 9 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.
