Zumaya (Playa de Itxurun) Swell Statistics, Summer: Surf with Light or Offshore Winds

This image shows only the swells directed at Zumaya (Playa de Itxurun) that coincided with light winds or offshore conditions over a normal northern hemisphere summer. It is based on 8737 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 illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the most common swell direction, shown by the largest spokes, was NW, whereas the the most common wind blows from the NNW. 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 32% of the time, equivalent to 29 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere summer but 5% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 5%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Zumaya (Playa de Itxurun) is exposed to open water swells, we calculate that clean surf can be found at Zumaya (Playa de Itxurun) about 32% of the time and that surf is messed up by onshore wind 63% of the time. This is means that we expect 86 days with waves in a typical northern hemisphere summer, of which 29 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.
