Statistiques de Vent de Noosa - Alexandria Bay, moyennes sur Juin depuis 2006
The figure illustrates how frequently and how strongly the wind blows from different directions over a normal June. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 2306 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Noosa - Alexandria Bay, located 40 km away (25 miles). There are not enough 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 most common wind at Noosa - Alexandria Bay blows from the SSE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Noosa - Alexandria Bay. Converseley, dominant spokes illustrate favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical 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 16% of the time (5 days in an average June). Over an average June winds stronger than >40kph (25mph) are expected on 2 days at Noosa - Alexandria Bay
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.
