Statistiques de Vent de Akito River Mouth and Reef, moyennes sur Été depuis 2006
The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical southern hemisphere summer. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 6931 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Akito River Mouth and Reef, located 44 km away (27 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 dominant wind at Akito River Mouth and Reef blows from the SE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Akito River Mouth and Reef. On the other hand, dominant spokes show 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 southern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (4 days each southern hemisphere summer) and blows offshore just 25% of the time (23 days in an average southern hemisphere summer). During a typical southern hemisphere summer winds stronger than >40kph (25mph) are expected on 4 days at Akito River Mouth and Reef
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.
