Castles Wind Stats

This chart illustrates how frequently and how strongly the wind blows from different directions through a typical August. 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 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Castles, located 46 km away (29 miles). There are not enough 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 Castles blows from the SW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Castles. On the other hand, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average August, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 8% of the time (2 days each August) and blows offshore 32% of the time (10 days in an average August). During a typical August winds stronger than >40kph (25mph) are expected on 4 days at Castles
