Acapulquito-Costa Azul Swell Statistics, All Year: Surf with Light or Offshore Winds
This image shows only the swells directed at Acapulquito-Costa Azul that coincided with light winds or offshore conditions over a normal year and is based upon 28044 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 illustrate increasing swell sizes and red represents 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 most common swell direction, shown by the largest spokes, was SSW, whereas the the prevailing wind blows from the NW. 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 62% of the time, equivalent to 226 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal year but 1.0% of the time we expect swell in the range 2-3m (6.5-10ft) 1.0%, equivalent to (4 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Acapulquito-Costa Azul is exposed to open water swells, we estimate that clean surf can be found at Acapulquito-Costa Azul about 62% of the time and that surf is spoilt by onshore wind 13% of the time. This is means that we expect 274 days with waves in a typical year, of which 226 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.
