Twin Rivers Wind Statistics, March averages since 2006
The figure shows how often and how strongly the wind blows from different directions through a typical March. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue showing the strongest winds. It is based on 2220 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Twin Rivers, located 86 km away (53 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 most common wind at Twin Rivers blows from the W. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Twin Rivers. On the other hand, dominant spokes represent 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 March, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 13% of the time (4 days each March) and blows offshore 44% of the time (11 days in an average March). In a typical March winds stronger than >40kph (25mph) are expected on 2 days at Twin Rivers
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.
