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

This image shows only the swells directed at Derrs that coincided with light winds or offshore conditions through a typical southern hemisphere autumn and is based upon 8682 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 red represents the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the most common swell direction, shown by the largest spokes, was SW, whereas the the most common wind blows from the SSE. 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 42% of the time, equivalent to 38 days. Open water swells exceeding >3m (>10ft) only arise 0.7% of the time in a typical southern hemisphere autumn, equivalent to just one day but 8% of the time we expect swell in the range 2-3m (6.5-10ft) 8%, equivalent to (7 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Derrs is exposed to open water swells, we think that that clean surf can be found at Derrs about 42% of the time and that surf is spoilt by onshore wind 58% of the time. This is means that we expect 91 days with waves in a typical southern hemisphere autumn, of which 38 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.
