Statistiques de Houle pour Niijima - Awaii, Hiver: 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 northern hemisphere winter. It is based on 8485 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 biggest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the prevailing swell direction, shown by the biggest spokes, was SSW, whereas the the prevailing wind blows from the NNW. 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 5% of the time, equivalent to 5 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere winter but 1.9% of the time we expect swell in the range 2-3m (6.5-10ft) 1.9%, equivalent to (2 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Niijima - Awaii is exposed to open water swells, we think that that clean surf can be found at Niijima - Awaii about 5% of the time and that surf is spoilt by onshore wind 6% of the time. This is means that we expect 10 days with waves in a typical northern hemisphere winter, of which 5 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.

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.
