Hells Gate Wind Stats

The rose diagram illustrates how often and how strongly the wind blows from different directions over a normal July. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue showing the strongest winds. It is based on 3720 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Hells Gate, located 24 km away (15 miles). There are not enough 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 Hells Gate blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Hells Gate. By contrast, dominant spokes represent 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 (the lightest shade of blue) about 9% of the time (3 days each July) and blows offshore 46% of the time (14 days in an average July). Over an average July winds stronger than >40kph (25mph) are expected on 2 days at Hells Gate
