Statistiques de Houle pour Johanna, Juillet: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Johanna that coincided with light winds or offshore conditions through a typical July. It is based on 2480 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 illustrates the biggest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the most common swell direction, shown by the largest spokes, was SW, whereas the the prevailing wind blows from the WNW. 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 30% of the time, equivalent to 9 days. Open water swells exceeding >3m (>10ft) only occur 1.9% of the time in a typical July, equivalent to just one day but 18% of the time we expect swell in the range 2-3m (6.5-10ft) 18%, equivalent to (6 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Johanna is exposed to open water swells, we calculate that clean surf can be found at Johanna about 30% of the time and that surf is spoilt by onshore wind 46% of the time. This is means that we expect 24 days with waves in a typical July, of which 9 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.
