Ferrel Swell Statistics, Spring: Surf with Light or Offshore Winds

This image shows only the swells directed at Ferrel that coincided with light winds or offshore conditions over a normal northern hemisphere spring. It is based on 8052 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 shows the biggest swells, greater than >3m (>10ft). In either 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 biggest spokes, was NW, whereas the the prevailing wind blows from the NNW. 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 16 days. Open water swells exceeding >3m (>10ft) only happen 0.6% of the time in a typical northern hemisphere spring, equivalent to just one day but 6% of the time we expect swell in the range 2-3m (6.5-10ft) 6%, equivalent to (5 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Ferrel is exposed to open water swells, we think that that clean surf can be found at Ferrel about 18% of the time and that surf is messed up by onshore wind 73% of the time. This is means that we expect 83 days with waves in a typical northern hemisphere spring, of which 16 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.
