Yarro Wind Statistics, All Year averages since 2006
The rose diagram illustrates how often and how strongly the wind blows from different directions over a normal year. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 26708 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Yarro, located 30 km away (19 miles). There are insufficient 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 dominant wind at Yarro blows from the NNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Yarro. 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 year, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 6% of the time (22 days each year) and blows offshore 9% of the time (29 days in an average year). Over an average year winds stronger than >40kph (25mph) are expected on 11 days at Yarro
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.
