Avalanche Wind Statistics, Ottobre averages since 2006
This chart describes how commonly and how strongly the wind blows from different directions through a typical October. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue showing the strongest winds. 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. Invevitably 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 graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Avalanche. On the other hand, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average October, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 14% of the time (4 days each October) and blows offshore 49% of the time (15 days in an average October). During a typical October winds exceeding >40kph (25mph) are not expected, but 1 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.
