Anglet - Marinella Swell Statistics, October: Surf with Light or Offshore Winds
The rose diagram shows only the swells directed at Anglet - Marinella that coincided with light winds or offshore conditions through a typical October and is based upon 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 represent increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how frequently that size swell occurs.
The diagram suggests that the most common swell direction, shown by the biggest spokes, was WNW, whereas the the dominant wind blows from the SSE. 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 39% of the time, equivalent to 12 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal October but 6% of the time we expect swell in the range 2-3m (6.5-10ft) 6%, equivalent to (2 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Anglet - Marinella is exposed to open water swells, we estimate that clean surf can be found at Anglet - Marinella about 39% of the time and that surf is spoilt by onshore wind 49% of the time. This is means that we expect 27 days with waves in a typical October, of which 12 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.
