Anna Maria Key Wind Statistieken, March gemiddelde vanaf 2006
The figure shows how commonly and how strongly the wind blows from different directions over a normal March. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2217 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Anna Maria Key, located 26 km away (16 miles). There are insufficient 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 Anna Maria Key blows from the NW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Anna Maria Key. Converseley, 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. During a typical March, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 5% of the time (2 days each March) and blows offshore 13% of the time (2 days in an average March). Over an average March wind stronger than >40kph (25mph) was predicted for only a single days at Anna Maria Key
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.
