Jabal Sur Swell Statistics, Summer: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Jabal Sur that coincided with light winds or offshore conditions over a normal 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 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 illustrates the largest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the most common swell direction, shown by the biggest spokes, was SSW (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 13% of the time, equivalent to 12 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere summer but 13% of the time we expect swell in the range 2-3m (6.5-10ft) 13%, equivalent to (12 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Jabal Sur is quite sheltered from open water swells, we think that that clean surf can be found at Jabal Sur about 13% of the time and that surf is blown out by onshore wind 51% of the time. This is means that we expect 58 days with waves in a typical northern hemisphere summer, of which 12 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.
