Noosa - Alexandria Bay Wind Statistics, March averages since 2006
This image describes how often and how strongly the wind blows from different directions through a typical March. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue showing the strongest winds. It is based on 2220 NWW3 forecasts of wind since since 2007, 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. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the prevailing wind at Noosa - Alexandria Bay blows from the SE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Noosa - Alexandria Bay. By contrast, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average March, the model suggests that winds are light enough for the sea to be glassy (light blue) about 0.3% of the time (0 days each March) and blows offshore just 0.6% of the time (0 days in an average March). During a typical March wind stronger than >40kph (25mph) was expected for only a single 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.
