Statistiques de Houle pour Downhill, Décembre: Vagues avec Vents Légers ou Favorables.

The rose diagram shows only the swells directed at Downhill that coincided with light winds or offshore conditions through a typical December and is based upon 2705 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 show increasing swell sizes and red represents the 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 most common swell direction, shown by the biggest spokes, was WNW, whereas the the dominant wind blows from the SW. 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 18% of the time, equivalent to 5 days. Open water swells exceeding >3m (>10ft) only occur 3% of the time in a typical December, equivalent to just one day but 8% of the time we expect swell in the range 2-3m (6.5-10ft) 8%, equivalent to (2 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Downhill is slightly protected from open water swells, we estimate that clean surf can be found at Downhill about 18% of the time and that surf is messed up by onshore wind 60% of the time. This is means that we expect 23 days with waves in a typical December, of which 5 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.
