Bunkers Wind Statistics, October averages since 2006
This image illustrates how frequently and how strongly the wind blows from different directions over a normal October. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Bunkers, located 34 km away (21 miles). There are too few 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 Bunkers blows from the WNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Bunkers. On the other hand, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical October, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 14% of the time (4 days each October) and blows offshore 32% of the time (10 days in an average October). Over an average October winds stronger than >40kph (25mph) are expected on 3 days at Bunkers
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
