Statistiques de Houle pour Jaco Beach, Toute l'Année: 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 through a typical year and is based upon 34628 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 red represents the highest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the dominant swell direction, shown by the largest spokes, was SSW, whereas the the dominant wind blows from the W. 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 45% of the time, equivalent to 164 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal year but 2% of the time we expect swell in the range 2-3m (6.5-10ft) 2%, equivalent to (7 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Jaco Beach is exposed to open water swells, we estimate that clean surf can be found at Jaco Beach about 45% of the time and that surf is spoilt by onshore wind 55% of the time. This is means that we expect 365 days with waves in a typical year, of which 164 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.
