Tubes Wind Stats

The figure describes how often and how strongly the wind blows from different directions over a normal September. 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 showing the strongest winds. It is based on 3360 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Tubes, located 52 km away (32 miles). There are not enough 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 Tubes blows from the SSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Tubes. Converseley, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical September, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 11% of the time (3 days each September) and blows offshore 57% of the time (10 days in an average September). Over an average September winds stronger than >40kph (25mph) are expected on 3 days at Tubes
