Barrack Point Wind Stats

The rose diagram illustrates how frequently and how strongly the wind blows from different directions through a typical August. 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 dark blue. It is based on 3574 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Barrack Point, located 13 km away (8 miles). There are too few 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 prevailing wind at Barrack Point blows from the E. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Barrack Point. Converseley, dominant spokes represent 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 (pale blue) about 6% of the time (2 days each August) and blows offshore 26% of the time (8 days in an average August). During a typical August winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Barrack Point
