Statistiques de Houle pour Moreton Island - Yellow Patch, Août: 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 August and is based upon 2480 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 biggest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the prevailing swell direction, shown by the biggest spokes, was ENE, whereas the the prevailing wind blows from the SSW. 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 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal August. 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 think that that clean surf can be found at Moreton Island - Yellow Patch about 3% of the time and that surf is messed up by onshore wind 3% of the time. This is means that we expect 2 days with waves in a typical August, 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.
