Big Beach Wind Stats

The rose diagram shows how commonly and how strongly the wind blows from different directions over a normal July. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 3720 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Big Beach, located 16 km away (10 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 prevailing wind at Big Beach blows from the SSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Big Beach. By contrast, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical July, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 1.7% of the time (1 days each July) and blows offshore just 45% of the time (14 days in an average July). Over an average July wind stronger than >40kph (25mph) was predicted for only a single days at Big Beach
