Estadísticas de Viento para Otago Peninsula - Allans Beach, Promedio de Invierno desde 2006
The figure describes how frequently and how strongly the wind blows from different directions over a normal 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 dark blue strongest. It is based on 7266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Otago Peninsula - Allans Beach, located 21 km away (13 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 Otago Peninsula - Allans Beach blows from the S. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Otago Peninsula - Allans Beach. By contrast, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical southern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 7% of the time (6 days each southern hemisphere winter) and blows offshore 29% of the time (26 days in an average southern hemisphere winter). Over an average southern hemisphere winter winds stronger than >40kph (25mph) are expected on 11 days at Otago Peninsula - Allans Beach
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.
