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 2232 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 represent increasing swell sizes and red shows the highest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell was forecast.
The diagram indicates that the most common swell direction, shown by the longest spokes, was NW, whereas the the dominant 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 occur in a normal July but 23% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 23%, equivalent to (7 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Bouznika Plage is quite sheltered from open water swells, we calculate that clean surf can be found at Bouznika Plage about 2.0% of the time and that surf is blown out by onshore wind 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.
