Estadísticas de Olas para Isla Negra, abril: 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 April and is based upon 2880 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the most common swell direction, shown by the largest spokes, was WNW, whereas the the most common wind blows from the SSW. 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 4% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal April. Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Isla Negra is exposed to open water swells, we calculate that clean surf can be found at Isla Negra about 4% of the time and that surf is spoilt by onshore wind 1.0% of the time. This is means that we expect 2 days with waves in a typical April, of which 1 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.
