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 through a typical March. It is based on 2082 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 show increasing swell sizes and red illustrates the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell was forecast.
The diagram suggests that the prevailing swell direction, shown by the longest 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 20% of the time, equivalent to 6 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur 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 proportion of these swells that coincided with forecast 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 20% of the time and that surf is blown out 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 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.
