Compton Bay Wind Statistics, April averages since 2006
This chart describes how frequently and how strongly the wind blows from different directions through a typical April. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 2159 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Compton Bay, located 18 km away (11 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 most common wind at Compton Bay blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Compton 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 April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 9% of the time (3 days each April) and blows offshore 15% of the time (1 days in an average April). In a typical April wind stronger than >40kph (25mph) was forecast for only a single days at Compton 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.
