Statistiques de Houle pour Moreton Island - Yellow Patch, Toute l'Année: Vagues avec Vents Légers ou Favorables.

The rose diagram shows only the swells directed at Moreton Island - Yellow Patch that coincided with light winds or offshore conditions over a normal year and is based upon 33260 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 happens.

The diagram indicates that the most common swell direction, shown by the largest spokes, was ENE, whereas the the dominant wind blows from the ESE. 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 3% of the time, equivalent to 11 days. Open water swells exceeding >3m (>10ft) only arise 0.2% of the time in a typical year, equivalent to just one day but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (11 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Moreton Island - Yellow Patch is quite sheltered from open water swells, we calculate that clean surf can be found at Moreton Island - Yellow Patch about 3% of the time and that surf is blown out by onshore wind 8% of the time. This is means that we expect 40 days with waves in a typical year, of which 11 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.
