Statistiques de Houle pour Juan Tornillo, Décembre: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Juan Tornillo that coincided with light winds or offshore conditions through a typical December. It is based on 2705 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 red illustrates highest swells greater than >3m (>10ft). In both graphs, 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 biggest spokes, was SW, whereas the the dominant 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 42% of the time, equivalent to 13 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal December. Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Juan Tornillo is exposed to open water swells, we calculate that clean surf can be found at Juan Tornillo about 42% of the time and that surf is spoilt by onshore wind 54% of the time. This is means that we expect 29 days with waves in a typical December, 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.
