Naval Jetties Wind Statistics, All Year averages since 2006
This chart shows how often and how strongly the wind blows from different directions through a typical year. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 26700 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Naval Jetties, located 32 km away (20 miles). There are insufficient 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 most common wind at Naval Jetties blows from the SSE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Naval Jetties. Converseley, dominant spokes show favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average year, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 7% of the time (26 days each year) and blows offshore 32% of the time (102 days in an average year). During a typical year winds stronger than >40kph (25mph) are expected on 15 days at Naval Jetties
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.
