Petten Wind Stats

This picture shows how often and how strongly the wind blows from different directions through a typical May. The largest 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 3192 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Petten, located 27 km away (17 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 prevailing wind at Petten blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Petten. By contrast, 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 May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 5% of the time (2 days each May) and blows offshore 14% of the time (3 days in an average May). During a typical May wind stronger than >40kph (25mph) was expected for only a single days at Petten
