Estadísticas de Olas para Avon Pier, Invierno: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Avon Pier that coincided with light winds or offshore conditions through a typical northern hemisphere winter. It is based on 6931 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 represent increasing swell sizes and red shows biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs.
The diagram implies that the dominant swell direction, shown by the largest spokes, was SSE, whereas the the prevailing wind blows from the NW. 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 water swells exceeding >3m (>10ft) only happen 0.8% of the time in a typical northern hemisphere winter, equivalent to just one day but 7% of the time we expect swell in the range 2-3m (6.5-10ft) 7%, equivalent to (6 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Avon Pier is exposed to open water swells, we think that that clean surf can be found at Avon Pier about 26% of the time and that surf is spoilt by onshore wind 21% of the time. This is means that we expect 43 days with waves in a typical northern hemisphere winter, 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.
