Waihau Bay Wind Statistics, February averages since 2006

The graph shows how frequently and how strongly the wind blows from different directions through a typical February. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Waihau Bay, located 15 km away (9 miles). There are too few 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 Waihau Bay blows from the NNE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Waihau Bay. By contrast, 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 February, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 5% of the time (1 days each February) and blows offshore 10% of the time (1 days in an average February). During a typical February wind stronger than >40kph (25mph) was forecast for only a single days at Waihau Bay

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.
