Victoria Bay Wind Stats

The rose diagram illustrates how frequently and how strongly the wind blows from different directions through a typical July. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue showing the strongest winds. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Victoria Bay, located 55 km away (34 miles). There are too few 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 Victoria Bay blows from the SSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Victoria Bay. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average July, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 12% of the time (4 days each July) and blows offshore 35% of the time (11 days in an average July). During a typical July winds stronger than >40kph (25mph) are expected on 4 days at Victoria Bay
