Onrus Wind Stats

The rose diagram shows how often and how strongly the wind blows from different directions through a typical May. The longest 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 the darkest shade of blue. It is based on 2838 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Onrus, located 18 km away (11 miles). There are insufficient recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Onrus blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Onrus. 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 May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 14% of the time (4 days each May) and blows offshore 59% of the time (18 days in an average May). In a typical May winds stronger than >40kph (25mph) are expected on 3 days at Onrus
