Backwash Wind Stats

The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue strongest. It is based on 3720 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Backwash, located 16 km away (10 miles). There are insufficient 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 prevailing wind at Backwash blows from the S. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Backwash. Converseley, 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 July, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 21% of the time (7 days each July) and blows offshore 80% of the time (24 days in an average July). Over an average July winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Backwash
