Bouznika Plage Swell Statistics, March: Surf with Light or Offshore Winds
This image shows only the swells directed at Bouznika Plage that coincided with light winds or offshore conditions over a normal March. It is based on 1724 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 illustrate increasing swell sizes and red shows 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 dominant swell direction, shown by the longest spokes, was NW, whereas the the most common 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 20% of the time, equivalent to 6 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal March but 19% of the time we expect swell in the range 2-3m (6.5-10ft) 19%, equivalent to (6 days). Taking into account the ratio of these swells that coincided with forecast 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 20% of the time and that surf is messed up by onshore wind 16% of the time. This is means that we expect 11 days with waves in a typical March, of which 6 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.
