Naval Jetties Wind Statistics, All Year averages since 2006
The figure describes how commonly and how strongly the wind blows from different directions over a normal year. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by deep blue. It is based on 26356 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 not enough 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. 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. During a typical year, the model suggests that winds are light enough for the sea to be glassy (light blue) about 7% of the time (26 days each year) and blows offshore 32% of the time (102 days in an average year). Over an average 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.
