Statistiques de Houle pour Niijima - Awaii, Toute l'Année: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Niijima - Awaii that coincided with light winds or offshore conditions through a typical year. It is based on 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 illustrates largest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the dominant swell direction, shown by the biggest spokes, was S, whereas the the most common wind blows from the NW. 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 10% of the time, equivalent to 36 days. Open water swells exceeding >3m (>10ft) only occur 0.3% of the time in a typical year, equivalent to just one day 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 Niijima - Awaii is exposed to open water swells, we calculate that clean surf can be found at Niijima - Awaii about 10% of the time and that surf is spoilt by onshore wind 16% of the time. This is means that we expect 95 days with waves in a typical year, of which 36 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.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
