Alkimos Wind Statistics, December averages since 2006
The figure illustrates how frequently and how strongly the wind blows from different directions over a normal December. The biggest 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 dark blue. It is based on 2457 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Alkimos, located 26 km away (16 miles). There are not enough 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 most common wind at Alkimos blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Alkimos. 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 December, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 5% of the time (2 days each December) and blows offshore 25% of the time (7 days in an average December). Over an average December winds exceeding >40kph (25mph) are not expected, but 6 have winds on the range 30-40 (19-25) at Alkimos
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.
