Tang Head Wind Stats

The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical August. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark blue. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Tang Head, located 41 km away (25 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 Tang Head blows from the NW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Tang Head. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average August, the model suggests that winds are light enough for the sea to be glassy (light blue) about 8% of the time (2 days each August) and blows offshore 37% of the time (11 days in an average August). During a typical August winds stronger than >40kph (25mph) are expected on 2 days at Tang Head
