Aln Estuary Wind Statistics, Luglio averages since 2006
The figure shows how often and how strongly the wind blows from different directions through a typical July. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue showing the strongest winds. It is based on 2479 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 insufficient recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Aln Estuary blows from the NE. If the rose diagram shows a close to circular outline, 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. Over an average July, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 10% of the time (3 days each July) and blows offshore 31% of the time (2 days in an average July). In a typical July winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) 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.
