Petten Wind Stats

The rose diagram illustrates how frequently and how strongly the wind blows from different directions through a typical July. The longest 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 3468 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Petten, located 27 km away (17 miles). There are not enough 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 prevailing wind at Petten blows from the NW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Petten. On the other hand, dominant spokes illustrate favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average July, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 6% of the time (2 days each July) and blows offshore 11% of the time (2 days in an average July). In a typical July wind stronger than >40kph (25mph) was expected for only a single days at Petten
