Arpoador Wind Statistieken, Winter gemiddelde vanaf 2006
The graph shows how commonly and how strongly the wind blows from different directions through a typical southern hemisphere winter. 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 the darkest shade of blue. It is based on 7266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Arpoador, located 21 km away (13 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 dominant wind at Arpoador blows from the SSE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Arpoador. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average southern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 29% of the time (26 days each southern hemisphere winter) and blows offshore 65% of the time (27 days in an average southern hemisphere winter). In a typical southern hemisphere winter winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Arpoador
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.
