Aln Estuary Wind Statistics, January averages since 2006
This chart illustrates how frequently and how strongly the wind blows from different directions over a normal January. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2371 NWW3 forecasts of wind since since 2007, 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. No doubt 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 diagram shows a close to circular outline, it means there is no strong bias in wind direction at Aln Estuary. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical January, the model suggests that winds are light enough for the sea to be glassy (light blue) about 3% of the time (1 days each January) and blows offshore just 25% of the time (4 days in an average January). Over an average January winds stronger than >40kph (25mph) are expected on 2 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.
