Estadísticas de Viento para Anna Maria Key, Promedio de Otoño desde 2006
The rose diagram shows how often and how strongly the wind blows from different directions through a typical northern hemisphere autumn. The longest 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 strongest. It is based on 7238 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Anna Maria Key, located 26 km away (16 miles). There are too few 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 dominant wind at Anna Maria Key blows from the NW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Anna Maria Key. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average northern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (7 days each northern hemisphere autumn) and blows offshore 20% of the time (6 days in an average northern hemisphere autumn). During a typical northern hemisphere autumn wind stronger than >40kph (25mph) was forecast 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.
