Estadísticas de Olas para Arica, septiembre: Olas con Vientos Ligeros o Terrales

The rose diagram shows only the swells directed at Arica that coincided with light winds or offshore conditions through a typical September. It is based on 2880 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 represent 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 commonly that size swell was forecast.

The diagram implies that the most common swell direction, shown by the largest spokes, was SW, whereas the the prevailing wind blows from the S. 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 0.5% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal September. Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Arica is exposed to open water swells, we calculate that clean surf can be found at Arica about 0.5% of the time and that surf is spoilt by onshore wind 100% of the time. This is means that we expect 30 days with waves in a typical September, of which 0 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.
