Bouznika Plage Swell Statistics, July: Surf with Light or Offshore Winds
This image shows only the swells directed at Bouznika Plage that coincided with light winds or offshore conditions through a typical July. It is based on 1984 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how often that size swell occurs.
The diagram indicates that the dominant swell direction, shown by the longest spokes, was NW, whereas the the most common 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 2.0% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal July but 25% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 25%, equivalent to (8 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Bouznika Plage is quite sheltered from open water swells, we think that that clean surf can be found at Bouznika Plage about 2.0% of the time and that surf is messed up by onshore wind 1.0% of the time. This is means that we expect 1 days with waves in a typical July, of which 1 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.
