Estadísticas de Olas para Gibson Steps, Verano: Olas con Vientos Ligeros o Terrales

This image shows only the swells directed at Gibson Steps that coincided with light winds or offshore conditions through a typical southern hemisphere summer. 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 illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow show increasing swell sizes and red shows the biggest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the largest spokes, was SW, whereas the the prevailing wind blows from the S. 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 14% of the time, equivalent to 13 days. Open water swells exceeding >3m (>10ft) only happen 1.2% of the time in a typical southern hemisphere summer, equivalent to just one day but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (8 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Gibson Steps is exposed to open water swells, we estimate that clean surf can be found at Gibson Steps about 14% of the time and that surf is messed up by onshore wind 79% of the time. This is means that we expect 85 days with waves in a typical southern hemisphere summer, of which 13 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.
