Macauleys Wind Stats

The rose diagram illustrates how commonly and how strongly the wind blows from different directions over a normal May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 3414 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Macauleys, located 34 km away (21 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 prevailing wind at Macauleys blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Macauleys. By contrast, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 12% of the time (4 days each May) and blows offshore 29% of the time (9 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 2 days at Macauleys
