Statistiques de Houle pour Sumner Bar, Janvier: Vagues avec Vents Légers ou Favorables.

The rose diagram shows only the swells directed at Sumner Bar that coincided with light winds or offshore conditions over a normal January. It is based on 2620 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 largest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the prevailing swell direction, shown by the largest spokes, was E, whereas the the most common 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 4% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal January. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Sumner Bar is slightly protected from open water swells, we calculate that clean surf can be found at Sumner Bar about 4% of the time and that surf is messed up by onshore wind 9% of the time. This is means that we expect 4 days with waves in a typical January, of which 1 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.
