Rock Wave Wind Statistics, December averages since 2006

The figure describes how often and how strongly the wind blows from different directions through a typical December. The biggest 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 1961 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Rock Wave, located 18 km away (11 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 Rock Wave blows from the S. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Rock Wave. On the other hand, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average December, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 5% of the time (2 days each December) and blows offshore 6% of the time (2 days in an average December). During a typical December wind stronger than >40kph (25mph) was expected for only a single days at Rock Wave

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.
