Statistiques de Houle pour Yzerfontein, Mai: Vagues avec Vents Légers ou Favorables.

The rose diagram shows only the swells directed at Yzerfontein that coincided with light winds or offshore conditions through a typical May and is based upon 2200 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 highest 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 dominant swell direction, shown by the biggest spokes, was SW, whereas the the dominant wind blows from the WSW. 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 30% of the time, equivalent to 9 days. Open water swells exceeding >3m (>10ft) only occur 4% of the time in a typical May, equivalent to just one day but 17% of the time we expect swell in the range 2-3m (6.5-10ft) 17%, equivalent to (5 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Yzerfontein is exposed to open water swells, we calculate that clean surf can be found at Yzerfontein about 30% of the time and that surf is blown out by onshore wind 68% of the time. This is means that we expect 30 days with waves in a typical May, of which 9 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.
