Statistiques de Houle pour Yport, Automne: Vagues avec Vents Légers ou Favorables.

The rose diagram shows only the swells directed at Yport that coincided with light winds or offshore conditions over a normal northern hemisphere autumn. It is based on 7239 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 highest 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 largest spokes, was WSW, whereas the the dominant wind blows from the WSW. 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 40% of the time, equivalent to 36 days. Open water swells exceeding >3m (>10ft) only happen 1.4% of the time in a typical northern hemisphere autumn, equivalent to just one day but 12% of the time we expect swell in the range 2-3m (6.5-10ft) 12%, equivalent to (11 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Yport is exposed to open water swells, we estimate that clean surf can be found at Yport about 40% of the time and that surf is spoilt by onshore wind 16% of the time. This is means that we expect 51 days with waves in a typical northern hemisphere autumn, of which 36 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.
