The Pass Wind Statistics, Aprile averages since 2006
This image describes how frequently and how strongly the wind blows from different directions over a normal April. 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 2159 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to The Pass, located 29 km away (18 miles). There are not enough recording stations world wide to use actual wind data. Without question 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 graph shows a fairly circular pattern, it means there is no strong bias in wind direction at The Pass. Converseley, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (1 days each April) and blows offshore just 15% of the time (0 days in an average April). Over an average April winds exceeding >40kph (25mph) are not expected, but 1 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.
