Statistiques de Houle pour Jack beach, Printemps: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Jack beach that coincided with light winds or offshore conditions over a normal northern hemisphere spring and is based upon 6580 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the prevailing swell direction, shown by the longest spokes, was NW, whereas the the most common wind blows from the N. 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 23% of the time, equivalent to 21 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal northern hemisphere spring but 4% of the time we expect swell in the range 2-3m (6.5-10ft) 4%, equivalent to (4 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Jack beach is exposed to open water swells, we calculate that clean surf can be found at Jack beach about 23% of the time and that surf is blown out by onshore wind 76% of the time. This is means that we expect 90 days with waves in a typical northern hemisphere spring, of which 21 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.
