Statistiques de Houle pour North Durras Reef, Toute l'Année: Vagues avec Vents Légers ou Favorables.

The rose diagram shows only the swells directed at North Durras Reef that coincided with light winds or offshore conditions over a normal year and is based upon 34628 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow represent increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In both graphs, 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 SE, whereas the the most common wind blows from the WNW. 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 29% of the time, equivalent to 106 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal year but 2% of the time we expect swell in the range 2-3m (6.5-10ft) 2%, equivalent to (7 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that North Durras Reef is exposed to open water swells, we calculate that clean surf can be found at North Durras Reef about 29% of the time and that surf is blown out by onshore wind 45% of the time. This is means that we expect 270 days with waves in a typical year, of which 106 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.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
