Statistiques de Houle pour Jaco Beach, Novembre: Vagues avec Vents Légers ou Favorables.

The rose diagram shows only the swells directed at Jaco Beach that coincided with light winds or offshore conditions over a normal November. It is based on 2809 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 red represents biggest swells greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the dominant swell direction, shown by the biggest spokes, was SSW, whereas the the prevailing wind blows from the WNW. 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 47% of the time, equivalent to 14 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal November but 22% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 22%, equivalent to (7 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Jaco Beach is exposed to open water swells, we think that that clean surf can be found at Jaco Beach about 47% of the time and that surf is spoilt by onshore wind 53% of the time. This is means that we expect 30 days with waves in a typical November, of which 14 days should be clean enough to surf.

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.
