Octagon House Wind Stats

The graph shows how commonly and how strongly the wind blows from different directions over a normal April. The biggest 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 2880 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Octagon House, located 15 km away (9 miles). There are insufficient 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 Octagon House blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Octagon House. Converseley, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical April, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 6% of the time (2 days each April) and blows offshore 15% of the time (3 days in an average April). Over an average April wind stronger than >40kph (25mph) was expected for only a single days at Octagon House
