Erromardie Wind Stats

The figure describes how commonly and how strongly the wind blows from different directions through a typical August. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by dark blue. It is based on 2976 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Erromardie, located 31 km away (19 miles). There are too few 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 dominant wind at Erromardie blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Erromardie. 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 August, the model suggests that winds are light enough for the sea to be glassy (light blue) about 28% of the time (9 days each August) and blows offshore 36% of the time (11 days in an average August). In a typical August winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Erromardie
