Statistiques de Houle pour Katwijk aan Zee, Octobre: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Katwijk aan Zee that coincided with light winds or offshore conditions over a normal October. It is based on 2973 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 highest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the most common swell direction, shown by the largest spokes, was NNW, 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 6% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal October. Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Katwijk aan Zee is exposed to open water swells, we think that that clean surf can be found at Katwijk aan Zee about 6% of the time and that surf is messed up by onshore wind 32% of the time. This is means that we expect 12 days with waves in a typical October, of which 2 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.
