Estadísticas de Olas para Atlantic Terrace, septiembre: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Atlantic Terrace that coincided with light winds or offshore conditions through a typical September. It is based on 2400 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 shows biggest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell was forecast.
The diagram implies that the prevailing swell direction, shown by the biggest spokes, was SE, whereas the the prevailing wind blows from the WSW. 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 8 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal September. Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Atlantic Terrace is exposed to open water swells, we estimate that clean surf can be found at Atlantic Terrace about 26% of the time and that surf is messed up by onshore wind 53% of the time. This is means that we expect 24 days with waves in a typical September, of which 8 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.
