Waimea Bay/Pinballs Wind Statistics, April averages since 2006
This picture illustrates how frequently and how strongly the wind blows from different directions over a normal April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue strongest. It is based on 2160 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Waimea Bay/Pinballs, located 40 km away (25 miles). There are too few recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Waimea Bay/Pinballs blows from the NNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Waimea Bay/Pinballs. On the other hand, 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 April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each April) and blows offshore just 36% of the time (11 days in an average April). Over an average April wind stronger than >40kph (25mph) was forecast for only a single days at Waimea Bay/Pinballs
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.
