Statistiques de Houle pour Johnshaven, Mai: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Johnshaven that coincided with light winds or offshore conditions through a typical May. It is based on 2696 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 red shows the largest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the prevailing swell direction, shown by the longest spokes, was SSE (which was the same as the most common wind direction). 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 0.4% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal May. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Johnshaven is slightly protected from open water swells, we calculate that clean surf can be found at Johnshaven about 0.4% of the time and that surf is messed up by onshore wind 8% of the time. This is means that we expect 2 days with waves in a typical May, of which 0 days should be surfable.
