Statistiques de Houle pour Jabal Zarain, Été: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Jabal Zarain that coincided with light winds or offshore conditions through a typical northern hemisphere summer. It is based on 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 illustrate increasing swell sizes and red illustrates the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the dominant swell direction, shown by the largest spokes, was SSW, whereas the the prevailing wind blows from the SW. 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 15% of the time, equivalent to 14 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere summer but 10% of the time we expect swell in the range 2-3m (6.5-10ft) 10%, equivalent to (9 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Jabal Zarain is exposed to open water swells, we think that that clean surf can be found at Jabal Zarain about 15% of the time and that surf is messed up by onshore wind 85% of the time. This is means that we expect 91 days with waves in a typical northern hemisphere summer, of which 14 days should be clean enough to surf.

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.
