Whitianga Wind Stats

The figure describes how frequently 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 implies the strength, with the darkest shade of blue strongest. It is based on 3347 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Whitianga, located 33 km away (21 miles). There are insufficient 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 dominant wind at Whitianga 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 Whitianga. On the other hand, 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 November, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 10% of the time (3 days each November) and blows offshore 45% of the time (2 days in an average November). Over an average November winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Whitianga
