The Pass Wind Statistics, Dicembre averages since 2006
This image shows how often and how strongly the wind blows from different directions over a normal December. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue showing the strongest winds. It is based on 2453 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to The Pass, located 29 km away (18 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 The Pass blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at The Pass. 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. During a typical December, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (1 days each December) and blows offshore just 21% of the time (0 days in an average December). Over an average December winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at The Pass
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.
