Aln Estuary Wind Statistics, February averages since 2006
The rose diagram shows how often and how strongly the wind blows from different directions over a normal February. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by deep blue. It is based on 2102 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 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 dominant wind at Aln Estuary blows from the NE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aln Estuary. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical February, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (1 days each February) and blows offshore just 27% of the time (3 days in an average February). Over an average February wind stronger than >40kph (25mph) was expected for only a single 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.
