Agnes Waters Wind Statistics, Summer averages since 2006
This image illustrates how frequently and how strongly the wind blows from different directions through a typical southern hemisphere summer. 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 6931 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Agnes Waters, located 27 km away (17 miles). There are too few 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 most common wind at Agnes Waters blows from the ENE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Agnes Waters. By contrast, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average southern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 4% of the time (4 days each southern hemisphere summer) and blows offshore just 5% of the time (4 days in an average southern hemisphere summer). During a typical southern hemisphere summer winds stronger than >40kph (25mph) are expected on 4 days at Agnes Waters
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.
