Aberdeen Wind Statistics, Summer averages since 2006
This chart shows how often and how strongly the wind blows from different directions through a typical northern hemisphere summer. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue strongest. It is based on 7264 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aberdeen, located 20 km away (12 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 Aberdeen blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aberdeen. On the other hand, dominant spokes illustrate 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 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 17% of the time (11 days in an average northern hemisphere summer). In a typical northern hemisphere summer wind stronger than >40kph (25mph) was predicted for only a single days at Aberdeen
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.
