Trial Harbour Wind Stats

This image describes how often and how strongly the wind blows from different directions over a normal November. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark blue. It is based on 3347 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Trial Harbour, located 16 km away (10 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 prevailing wind at Trial Harbour blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Trial Harbour. 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 November, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 13% of the time (4 days each November) and blows offshore 23% of the time (7 days in an average November). Over an average November winds stronger than >40kph (25mph) are expected on 3 days at Trial Harbour
