The figure shows how frequently and how strongly the wind blows from different directions through a typical January. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue strongest. It is based on 1728 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Moody Beach, located 31 km away (19 miles). There are not enough 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 prevailing wind at Moody Beach blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Moody Beach. On the other hand, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average January, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (1 days each January) and blows offshore just 26% of the time (5 days in an average January). During a typical January winds stronger than >40kph (25mph) are expected on 2 days at Moody Beach
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.
