Marsden Bay Wind Stats

The figure illustrates how frequently and how strongly the wind blows from different directions through a typical June. 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 2872 NWW3 forecasts of wind since since 2008, at 3hr intervals, for the closest NWW3 model node to Marsden Bay, located 25 km away (16 miles). There are insufficient 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 Marsden Bay blows from the NNE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Marsden Bay. On the other hand, 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 June, the model suggests that winds are light enough for the sea to be glassy (light blue) about 11% of the time (3 days each June) and blows offshore 29% of the time (1 days in an average June). During a typical June wind stronger than >40kph (25mph) was predicted for only a single days at Marsden Bay
