This chart describes how commonly and how strongly the wind blows from different directions through a typical year. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 20364 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Waitpinga, located 15 km away (9 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 most common wind at Waitpinga blows from the SSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Waitpinga. Converseley, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average year, the model suggests that winds are light enough for the sea to be glassy (light blue) about 12% of the time (44 days each year) and blows offshore 33% of the time (120 days in an average year). In a typical year winds stronger than >40kph (25mph) are expected on 7 days at Waitpinga
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.
