The figure shows how frequently and how strongly the wind blows from different directions through a typical June. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 1594 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Zorba, located 9 km away (6 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 prevailing wind at Zorba blows from the S. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Zorba. On the other hand, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 7% of the time (2 days each June) and blows offshore 24% of the time (7 days in an average June). During a typical June wind stronger than >40kph (25mph) was predicted for only a single days at Zorba
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.
