Statistiques de Houle pour Mahanga Point, Printemps: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Mahanga Point that coincided with light winds or offshore conditions over a normal southern hemisphere spring. It is based on 7252 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 illustrate increasing swell sizes and red illustrates highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the dominant swell direction, shown by the largest spokes, was ENE, whereas the the dominant wind blows from the NW. 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 13% of the time, equivalent to 12 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal southern hemisphere spring but 1.8% of the time we expect swell in the range 2-3m (6.5-10ft) 1.8%, equivalent to (2 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Mahanga Point is exposed to open water swells, we calculate that clean surf can be found at Mahanga Point about 13% of the time and that surf is spoilt by onshore wind 20% of the time. This is means that we expect 30 days with waves in a typical southern hemisphere spring, of which 12 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.
