Jabal Zarain Swell Statistics, Spring: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Jabal Zarain that coincided with light winds or offshore conditions through a typical northern hemisphere spring. It is based on 8052 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 show increasing swell sizes and red illustrates the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the dominant swell direction, shown by the largest spokes, was S, whereas the the most common wind blows from the WSW. 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 10% of the time, equivalent to 9 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere spring. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Jabal Zarain is exposed to open water swells, we calculate that clean surf can be found at Jabal Zarain about 10% of the time and that surf is blown out by onshore wind 73% of the time. This is means that we expect 76 days with waves in a typical northern hemisphere spring, 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.
