Arrieta Swell Statistics, Winter: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Arrieta that coincided with light winds or offshore conditions over a normal northern hemisphere winter and is based upon 8485 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 shows biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the most common swell direction, shown by the longest spokes, was NNW, whereas the the prevailing wind blows from the NE. 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 6% of the time, equivalent to 5 days. Open water swells exceeding >3m (>10ft) only arise 0.9% of the time in a typical northern hemisphere winter, equivalent to just one day but 5% of the time we expect swell in the range 2-3m (6.5-10ft) 5%, equivalent to (5 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Arrieta is quite sheltered from open water swells, we estimate that clean surf can be found at Arrieta about 6% of the time and that surf is blown out by onshore wind 34% of the time. This is means that we expect 36 days with waves in a typical northern hemisphere winter, of which 5 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.
