Extensions Wind Stats

The figure describes how frequently and how strongly the wind blows from different directions over a normal June. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2786 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Extensions, located 18 km away (11 miles). There are not enough 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 most common wind at Extensions 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 Extensions. By contrast, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical June, the model suggests that winds are light enough for the sea to be glassy (light blue) about 6% of the time (2 days each June) and blows offshore 25% of the time (8 days in an average June). Over an average June winds stronger than >40kph (25mph) are expected on 7 days at Extensions
