Estadísticas de Olas para Derrs, Verano: 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 summer. It is based on 7765 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow illustrate increasing swell sizes and red represents biggest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the most common swell direction, shown by the longest spokes, was SW, whereas the the prevailing 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 26% of the time, equivalent to 24 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal southern hemisphere summer but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (3 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Derrs is exposed to open water swells, we estimate that clean surf can be found at Derrs about 26% of the time and that surf is blown out by onshore wind 74% of the time. This is means that we expect 91 days with waves in a typical southern hemisphere summer, of which 24 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.
