Acapulquito-Costa Azul Golf Statistieken, Lente: Golven met Licht of Offshore Winden
The rose diagram shows only the swells directed at Acapulquito-Costa Azul that coincided with light winds or offshore conditions over a normal northern hemisphere spring and is based upon 6580 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 illustrate increasing swell sizes and red shows biggest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell occurs.
The diagram indicates 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 75% of the time, equivalent to 68 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere spring but 28% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 28%, equivalent to (25 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 calculate that clean surf can be found at Acapulquito-Costa Azul about 75% of the time and that surf is blown out by onshore wind 11% of the time. This is means that we expect 78 days with waves in a typical northern hemisphere spring, of which 68 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.
