Hess Wind Stats

The rose diagram illustrates how commonly and how strongly the wind blows from different directions over a normal November. The biggest 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 3347 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Hess, located 39 km away (24 miles). There are insufficient 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 dominant wind at Hess 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 Hess. Converseley, dominant spokes represent favoured directions, and the more deep 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 (light blue) about 8% of the time (2 days each November) and blows offshore 19% of the time (5 days in an average November). Over an average November wind stronger than >40kph (25mph) was predicted for only a single days at Hess
