This chart describes how often and how strongly the wind blows from different directions over a normal northern hemisphere summer. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 5046 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Wiggins Pass, located 36 km away (22 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 dominant wind at Wiggins Pass blows from the ESE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Wiggins Pass. By contrast, 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 northern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 7% of the time (6 days each northern hemisphere summer) and blows offshore 28% of the time (7 days in an average northern hemisphere summer). Over an average northern hemisphere summer winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Wiggins 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.
