Teahupoo Wind Statistics, Winter averages since 2006
The rose diagram describes how often and how strongly the wind blows from different directions through a typical southern hemisphere winter. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 6880 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Teahupoo, located 31 km away (19 miles). There are insufficient 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 most common wind at Teahupoo blows from the S. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Teahupoo. Converseley, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average southern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (7 days each southern hemisphere winter) and blows offshore 32% of the time (29 days in an average southern hemisphere winter). In a typical southern hemisphere winter winds stronger than >40kph (25mph) are expected on 3 days at Teahupoo
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.
