Azarujinha Wind Statistics, Spring averages since 2006
The graph describes how often and how strongly the wind blows from different directions over a normal northern hemisphere spring. The longest 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 deep blue. It is based on 6580 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Azarujinha, located 24 km away (15 miles). There are insufficient 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 most common wind at Azarujinha blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Azarujinha. By contrast, 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 spring, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 1.7% of the time (2 days each northern hemisphere spring) and blows offshore just 7% of the time (5 days in an average northern hemisphere spring). Over an average northern hemisphere spring wind stronger than >40kph (25mph) was forecast for only a single days at Azarujinha
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.
