Jardim do Mar Swell Statistics, Summer: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Jardim do Mar that coincided with light winds or offshore conditions through a typical northern hemisphere summer. It is based on 8738 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 illustrates the largest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the biggest spokes, was WNW, whereas the the most common wind blows from the N. 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 34% of the time, equivalent to 31 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere summer but 12% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 12%, equivalent to (11 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Jardim do Mar is exposed to open water swells, we think that that clean surf can be found at Jardim do Mar about 34% of the time and that surf is spoilt by onshore wind 7% of the time. This is means that we expect 37 days with waves in a typical northern hemisphere summer, of which 31 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.
