Estadísticas de Olas para Islares, Otoño: Olas con Vientos Ligeros o Terrales

This image shows only the swells directed at Islares that coincided with light winds or offshore conditions over a normal northern hemisphere autumn. It is based on 8476 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 show increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the largest spokes, was NW, whereas the the dominant wind blows from the SSW. 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 23% of the time, equivalent to 21 days. Open water swells exceeding >3m (>10ft) only arise 1.6% of the time in a typical northern hemisphere autumn, equivalent to just one day but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (8 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Islares is slightly protected from open water swells, we think that that clean surf can be found at Islares about 23% of the time and that surf is messed up by onshore wind 32% of the time. This is means that we expect 50 days with waves in a typical northern hemisphere autumn, of which 21 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.
