Corbyns Cove Wind Statistics, Winter averages since 2006
The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical northern hemisphere winter. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 5470 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Corbyns Cove, located 30 km away (19 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 Corbyns Cove blows from the SSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Corbyns Cove. 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. Over an average northern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (4 days each northern hemisphere winter) and blows offshore just 5% of the time (0 days in an average northern hemisphere winter). In a typical northern hemisphere winter winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Corbyns Cove
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.
