The graph describes how frequently and how strongly the wind blows from different directions through a typical June. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 1608 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to The Bowl, located 19 km away (12 miles). There are too few recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the prevailing wind at The Bowl blows from the SSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at The Bowl. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average June, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (1 days each June) and blows offshore just 60% of the time (18 days in an average June). During a typical June wind stronger than >40kph (25mph) was forecast for only a single days at The Bowl
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.
