Herolds Bay Wind Statistics, June averages since 2006
This image shows how often and how strongly the wind blows from different directions through a typical June. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue showing the strongest winds. It is based on 2306 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Herolds Bay, located 52 km away (32 miles). There are too few 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 Herolds Bay 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 Herolds Bay. By contrast, dominant spokes illustrate 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 June, the model suggests that winds are light enough for the sea to be glassy (light blue) about 1.6% of the time (0 days each June) and blows offshore just 6% of the time (2 days in an average June). During a typical June wind stronger than >40kph (25mph) was expected for only a single days at Herolds 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.
