Collignon Wind Stats

The rose diagram illustrates how commonly and how strongly the wind blows from different directions through a typical April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by deep blue. It is based on 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Collignon, located 38 km away (24 miles). There are insufficient 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 Collignon blows from the WNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Collignon. On the other hand, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average April, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 9% of the time (3 days each April) and blows offshore 24% of the time (6 days in an average April). During a typical April wind stronger than >40kph (25mph) was forecast for only a single days at Collignon
