Arguineguin Golf Statistieken, February: Golven met Licht of Offshore Winden
This image shows only the swells directed at Arguineguin that coincided with light winds or offshore conditions over a normal February. It is based on 2102 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 represent increasing swell sizes and red shows the largest swells, greater than >3m (>10ft). In both graphs, 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 biggest spokes, was SW, whereas the the most common wind blows from the NNE. 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 2% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal February. Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Arguineguin is exposed to open water swells, we think that that clean surf can be found at Arguineguin about 2% of the time and that surf is blown out by onshore wind 1.0% of the time. This is means that we expect 1 days with waves in a typical February, 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.
