Estadísticas de Viento para Aln Estuary, Promedio de Otoño desde 2006
The rose diagram illustrates how frequently and how strongly the wind blows from different directions over a normal northern hemisphere autumn. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 7251 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aln Estuary, located 14 km away (9 miles). There are too few 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 Aln Estuary blows from the NE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Aln Estuary. 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 northern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 5% of the time (5 days each northern hemisphere autumn) and blows offshore 26% of the time (9 days in an average northern hemisphere autumn). Over an average northern hemisphere autumn winds stronger than >40kph (25mph) are expected on 4 days at Aln Estuary
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.
