Acapulquito-Costa Azul Swell Statistics, October: 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 through a typical October and is based upon 2480 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 largest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs.
The diagram suggests that the dominant swell direction, shown by the longest spokes, was SSW, whereas the the most common 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 72% of the time, equivalent to 22 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal October 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 Acapulquito-Costa Azul is exposed to open water swells, we think that that clean surf can be found at Acapulquito-Costa Azul about 72% of the time and that surf is blown out by onshore wind 16% of the time. This is means that we expect 27 days with waves in a typical October, of which 22 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.
