Church Bay Swell Statistics, Summer: Surf with Light or Offshore Winds

This image shows only the swells directed at Church Bay that coincided with light winds or offshore conditions over a normal northern hemisphere summer and is based upon 5876 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 show increasing swell sizes and red represents the largest swells, greater than >3m (>10ft). In both graphs, 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 longest spokes, was NNW, whereas the the most common wind blows from the WSW. 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 0% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere summer. Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Church Bay is slightly protected from open water swells, we think that that clean surf can be found at Church Bay about 0% of the time and that surf is messed up by onshore wind 2.0% of the time. This is means that we expect 2 days with waves in a typical northern hemisphere summer, of which 0 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.
