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

This image shows only the swells directed at Grim Ness 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 show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and red illustrates biggest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the dominant swell direction, shown by the largest spokes, was NNE, whereas the the prevailing wind blows from the SW. 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 8% of the time, equivalent to 7 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere autumn but 1.7% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 1.7%, equivalent to (2 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Grim Ness is exposed to open water swells, we think that that clean surf can be found at Grim Ness about 8% of the time and that surf is spoilt by onshore wind 18% of the time. This is means that we expect 24 days with waves in a typical northern hemisphere autumn, of which 7 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.
