Agadir Swell Statistics, Autumn: Surf with Light or Offshore Winds
This image shows only the swells directed at Agadir that coincided with light winds or offshore conditions through a typical northern hemisphere autumn. It is based on 7252 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 illustrates the biggest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell happens.
The diagram implies that the dominant swell direction, shown by the largest spokes, was NW, whereas the the prevailing wind blows from the N. 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 23% of the time, equivalent to 21 days. Expect open water swells to exceed >3m (>10ft) 3% of the time (3 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Agadir is quite sheltered from open water swells, we calculate that clean surf can be found at Agadir about 23% of the time and that surf is blown out by onshore wind 11% of the time. This is means that we expect 31 days with waves in a typical northern hemisphere autumn, of which 21 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.
