Balnarring Point Wind Statistics, All Year averages since 2006
The graph shows how frequently and how strongly the wind blows from different directions through a typical year. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark blue. It is based on 25429 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Balnarring Point, located 15 km away (9 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 dominant wind at Balnarring Point blows from the SW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Balnarring Point. Converseley, dominant spokes show favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average year, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 10% of the time (36 days each year) and blows offshore 43% of the time (33 days in an average year). In a typical year winds stronger than >40kph (25mph) are expected on 29 days at Balnarring Point
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.
