Statistiques de Houle pour Dona Ana, Novembre: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Dona Ana that coincided with light winds or offshore conditions over a normal November. It is based on 2801 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the dominant swell direction, shown by the largest spokes, was SSW, whereas the the most common wind blows from the WNW. 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 52% of the time, equivalent to 16 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal November but 22% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 22%, equivalent to (7 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Dona Ana is exposed to open water swells, we think that that clean surf can be found at Dona Ana about 52% of the time and that surf is messed up by onshore wind 48% of the time. This is means that we expect 30 days with waves in a typical November, of which 16 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.
