Nettley Bay Reefs Wind Stats

The figure describes how often and how strongly the wind blows from different directions through a typical October. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 2976 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Nettley Bay Reefs, located 13 km away (8 miles). There are too few 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 dominant wind at Nettley Bay Reefs blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Nettley Bay Reefs. 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. Over an average October, the model suggests that winds are light enough for the sea to be glassy (light blue) about 5% of the time (2 days each October) and blows offshore 19% of the time (6 days in an average October). During a typical October winds stronger than >40kph (25mph) are expected on 7 days at Nettley Bay Reefs
