Twin Rivers Wind Statistics, March averages since 2006
The rose diagram shows how commonly and how strongly the wind blows from different directions over a normal March. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2098 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 not enough 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 prevailing wind at Twin Rivers blows from the W. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Twin Rivers. By contrast, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical March, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 13% of the time (4 days each March) and blows offshore 42% of the time (10 days in an average March). Over an average 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.
