A Street Golf Statistieken, November: Golven met Licht of Offshore Winden
This image shows only the swells directed at A Street that coincided with light winds or offshore conditions over a normal November and is based upon 2387 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 biggest swells greater than >3m (>10ft) are shown in red. In each 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 largest spokes, was ESE, whereas the the prevailing 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 1.2% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal November. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that A Street is slightly protected from open water swells, we think that that clean surf can be found at A Street about 1.2% of the time and that surf is blown out by onshore wind 3% of the time. This is means that we expect 1 days with waves in a typical November, of which 0 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.
