Estadísticas de Olas para Airport Lefts, agosto: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Airport Lefts that coincided with light winds or offshore conditions through a typical August. It is based on 2480 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 represents largest swells greater than >3m (>10ft). In each graph, 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 SW, whereas the the most common wind blows from the ESE. 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 100% of the time, equivalent to 31 days. Open water swells exceeding >3m (>10ft) only happen 2% of the time in a typical August, equivalent to just one day but 69% of the time we expect swell in the range 2-3m (6.5-10ft) 69%, equivalent to (21 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Airport Lefts is exposed to open water swells, we estimate that clean surf can be found at Airport Lefts about 100% of the time and that surf is messed up by onshore wind 0% of the time. This is means that we expect 31 days with waves in a typical August, of which 31 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.
