Agnes Waters Wind Statistics, November averages since 2006
This picture describes how commonly and how strongly the wind blows from different directions over a normal November. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by deep blue. It is based on 2387 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. No doubt 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 diagram shows a close to circular outline, it means there is no strong bias in wind direction at Agnes Waters. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical November, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each November) and blows offshore just 4% of the time (1 days in an average November). Over an average November winds exceeding >40kph (25mph) are not expected, but 3 have winds on the range 30-40 (19-25) 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.
