Swansea Point Wind Stats

This chart shows how frequently and how strongly the wind blows from different directions through a typical July. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Swansea Point, located 37 km away (23 miles). There are too few recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the most common wind at Swansea Point blows from the S. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Swansea Point. On the other hand, dominant spokes show 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 July, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 5% of the time (2 days each July) and blows offshore 38% of the time (4 days in an average July). During a typical July winds stronger than >40kph (25mph) are expected on 2 days at Swansea Point
