Estadísticas de Olas para Isla Negra, Verano: Olas con Vientos Ligeros o Terrales

The rose diagram shows only the swells directed at Isla Negra that coincided with light winds or offshore conditions through a typical southern hemisphere summer and is based upon 8485 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 represents the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the dominant swell direction, shown by the longest spokes, was WNW, 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 17% of the time, equivalent to 15 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal southern hemisphere summer 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 fraction of these swells that coincided with expected offshore winds, and given the fact that Isla Negra is exposed to open water swells, we think that that clean surf can be found at Isla Negra about 17% of the time and that surf is blown out by onshore wind 6% of the time. This is means that we expect 21 days with waves in a typical southern hemisphere summer, of which 15 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.
