Awatoto Rivermouth Wind Statistics, Summer averages since 2006
This chart shows how often and how strongly the wind blows from different directions over a normal southern hemisphere summer. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 6931 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 not enough recording stations world wide to use actual wind data. No doubt 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. On the other hand, 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 southern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (light blue) about 18% of the time (16 days each southern hemisphere summer) and blows offshore 32% of the time (25 days in an average southern hemisphere summer). Over an average southern hemisphere summer winds exceeding >40kph (25mph) are not expected, but 3 have winds on the range 30-40 (19-25) 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.
