Avalanche Wind Statistics, Julho averages since 2006
The figure illustrates how often and how strongly the wind blows from different directions over a normal July. The largest 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 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Avalanche, located 41 km away (25 miles). There are too few recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Avalanche blows from the NNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Avalanche. 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. During a typical July, the model suggests that winds are light enough for the sea to be glassy (light blue) about 0.5% of the time (0 days each July) and blows offshore just 5% of the time (2 days in an average July). Over an average July winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Avalanche
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.
