Joaquina Swell Statistics, Autumn: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Joaquina that coincided with light winds or offshore conditions over a normal southern hemisphere autumn. 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 show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and red shows the largest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the dominant swell direction, shown by the largest spokes, was SE, whereas the the most common wind blows from the E. 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 24% of the time, equivalent to 22 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal southern hemisphere autumn but 9% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 9%, equivalent to (8 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Joaquina is exposed to open water swells, we think that that clean surf can be found at Joaquina about 24% of the time and that surf is blown out by onshore wind 46% of the time. This is means that we expect 64 days with waves in a typical southern hemisphere autumn, of which 22 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.
