Newcastle - The Wedge Wind Statistics, April averages since 2006
This picture illustrates how frequently and how strongly the wind blows from different directions over a normal April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue strongest. It is based on 2160 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Newcastle - The Wedge, located 21 km away (13 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 most common wind at Newcastle - The Wedge blows from the ESE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Newcastle - The Wedge. By contrast, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 7% of the time (2 days each April) and blows offshore 21% of the time (7 days in an average April). Over an average April winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Newcastle - The Wedge
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.
