Awatoto Rivermouth Wind Statistieken, Lente gemiddelde vanaf 2006
This picture describes how frequently and how strongly the wind blows from different directions over a normal southern hemisphere spring. The biggest 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 7249 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Awatoto Rivermouth, located 7 km away (4 miles). There are insufficient 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 prevailing wind at Awatoto Rivermouth blows from the ESE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Awatoto Rivermouth. Converseley, dominant spokes show 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 spring, the model suggests that winds are light enough for the sea to be glassy (light blue) about 14% of the time (13 days each southern hemisphere spring) and blows offshore 30% of the time (23 days in an average southern hemisphere spring). Over an average southern hemisphere spring wind stronger than >40kph (25mph) was predicted for only a single days at Awatoto Rivermouth
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.
