Statistiques de Houle pour Dumbea Left, Hiver: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Dumbea Left that coincided with light winds or offshore conditions through a typical southern hemisphere winter and is based upon 8738 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 frequently that size swell happens.

The diagram suggests that the dominant swell direction, shown by the biggest spokes, was S, whereas the the dominant wind blows from the SE. 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 31% of the time, equivalent to 28 days. Open water swells exceeding >3m (>10ft) only arise 0.7% of the time in a typical southern hemisphere winter, equivalent to just one day but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (8 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Dumbea Left is exposed to open water swells, we calculate that clean surf can be found at Dumbea Left about 31% of the time and that surf is messed up by onshore wind 57% of the time. This is means that we expect 80 days with waves in a typical southern hemisphere winter, of which 28 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.

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.
