Algarrobo Swell Statistics, August: Surf with Light or Offshore Winds

This image shows only the swells directed at Algarrobo that coincided with light winds or offshore conditions over a normal August and is based upon 2976 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 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 happens.

The diagram suggests that the prevailing swell direction, shown by the longest spokes, was WSW, whereas the the dominant wind blows from the SSW. 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 20% of the time, equivalent to 6 days. Open water swells exceeding >3m (>10ft) only arise 3% of the time in a typical August, equivalent to just one day but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (3 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Algarrobo is exposed to open water swells, we estimate that clean surf can be found at Algarrobo about 20% of the time and that surf is blown out by onshore wind 79% of the time. This is means that we expect 31 days with waves in a typical August, of which 6 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.
