Arinaga Wind Statistieken, August gemiddelde vanaf 2006
The graph describes how often and how strongly the wind blows from different directions through a typical August. 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 the darkest shade of blue. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Arinaga, located 42 km away (26 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 dominant wind at Arinaga blows from the N. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Arinaga. On the other hand, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average August, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 0.1% of the time (0 days each August) and blows offshore just 0.2% of the time (0 days in an average August). In a typical August wind stronger than >40kph (25mph) was expected for only a single days at Arinaga
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.
