Backdoor Wind Stats

This image describes how often and how strongly the wind blows from different directions through a typical May. The longest 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 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Backdoor, located 11 km away (7 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 Backdoor blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Backdoor. Converseley, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (2 days each May) and blows offshore 14% of the time (5 days in an average May). During a typical May wind stronger than >40kph (25mph) was forecast for only a single days at Backdoor
