Tourmaline Wind Statistics, February averages since 2006
The graph describes how frequently and how strongly the wind blows from different directions through a typical February. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 1808 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Tourmaline, located 30 km away (19 miles). There are not enough 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 Tourmaline blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Tourmaline. On the other hand, 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. Over an average February, the model suggests that winds are light enough for the sea to be glassy (light blue) about 37% of the time (10 days each February) and blows offshore 48% of the time (13 days in an average February). In a typical February winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Tourmaline
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.
