Castles Beach Wind Stats

This picture shows how often and how strongly the wind blows from different directions over a normal May. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue showing the strongest winds. It is based on 3406 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Castles Beach, located 27 km away (17 miles). There are insufficient 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 most common wind at Castles Beach blows from the NE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Castles Beach. By contrast, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each May) and blows offshore just 4% of the time (1 days in an average May). Over an average May wind stronger than >40kph (25mph) was expected for only a single days at Castles Beach
