Oxwich Bay Wind Stats

The figure shows how commonly and how strongly the wind blows from different directions through a typical September. The largest 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 2878 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Oxwich Bay, located 13 km away (8 miles). There are too few 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 Oxwich Bay blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Oxwich Bay. 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. Over an average September, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 10% of the time (3 days each September) and blows offshore 37% of the time (0 days in an average September). During a typical September winds stronger than >40kph (25mph) are expected on 2 days at Oxwich Bay
