Aan Golf Statistieken, Hele Jaar: Golven met Licht of Offshore Winden

This image shows only the swells directed at Aan that coincided with light winds or offshore conditions over a normal year. It is based on 28044 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow represent increasing swell sizes and red shows highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the prevailing swell direction, shown by the longest spokes, was SW, whereas the the dominant wind blows from the SSE. 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 18% of the time, equivalent to 66 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal year but 4% of the time we expect swell in the range 2-3m (6.5-10ft) 4%, equivalent to (15 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Aan is slightly protected from open water swells, we calculate that clean surf can be found at Aan about 18% of the time and that surf is blown out by onshore wind 66% of the time. This is means that we expect 307 days with waves in a typical year, of which 66 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.
