Owahanga Wind Stats

The figure describes how often and how strongly the wind blows from different directions through a typical October. The longest 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 the darkest shade of blue. It is based on 2976 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Owahanga, located 37 km away (23 miles). There are not enough recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Owahanga blows from the SE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Owahanga. 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. Over an average October, 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 October) and blows offshore just 24% of the time (7 days in an average October). During a typical October winds stronger than >40kph (25mph) are expected on 2 days at Owahanga
