Trial Harbour Wind Stats

The rose diagram describes how frequently and how strongly the wind blows from different directions through a typical June. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 3384 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 insufficient 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 most common wind at Trial Harbour blows from the WSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Trial Harbour. 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. Over an average June, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 11% of the time (3 days each June) and blows offshore 22% of the time (7 days in an average June). In a typical June winds stronger than >40kph (25mph) are expected on 4 days at Trial Harbour
