Statistiques de Vent de Apua Point, moyennes sur Mars depuis 2006
This chart shows how often and how strongly the wind blows from different directions through a typical March. The longest 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 dark blue. It is based on 2220 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Apua Point, located 35 km away (22 miles). There are insufficient 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 Apua Point blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Apua Point. By contrast, 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 March, the model suggests that winds are light enough for the sea to be glassy (light blue) about 2% of the time (1 days each March) and blows offshore just 2% of the time (1 days in an average March). In a typical March wind stronger than >40kph (25mph) was forecast for only a single days at Apua Point
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.
