Anna Maria Key Wind Statistics, May averages since 2006
This image describes how frequently and how strongly the wind blows from different directions through a typical May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue showing the strongest winds. It is based on 2195 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 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 Anna Maria Key blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Anna Maria Key. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 5% of the time (2 days each May) and blows offshore 10% of the time (1 days in an average May). During a typical May winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) 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.
