Statistiques de Houle pour Bali Bay (Glen Reef), Toute l'Année: Toutes Houles – Tous Vents

The rose diagram describes the range of swells directed at Bali Bay (Glen Reef) over a normal year and is based upon 34628 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind or surf right at the shore so we have chosen the most applicable grid node based on what we know about Bali Bay (Glen Reef). In this particular case the best grid node is 35 km away (22 miles).

The rose diagram shows the distribution of swell sizes and directions, while the graph at the bottom shows the same thing but lacks direction information. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. These occurred only 98% of the time. Green and yellow show increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the prevailing swell direction, shown by the biggest spokes, was WNW, whereas the the dominant wind blows from the SSW. Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from Bali Bay (Glen Reef) and offshore. We combine these with the no surf category of the bar chart. To simplify things we don't show these in the rose plot. Because wind determines whether or not waves are surfable at Bali Bay (Glen Reef), you can select a similar diagram that shows only the swells that were predicted to coincide with glassy or offshore wind conditions. During a typical year, swells large enough to cause good for surfing waves at Bali Bay (Glen Reef) run for about 2.0% of the time.

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.
