Erromardie Wind Stats

This image shows how frequently and how strongly the wind blows from different directions through a typical May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue showing the strongest winds. It is based on 2838 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Erromardie, located 31 km away (19 miles). There are insufficient 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 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. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 21% of the time (7 days each May) and blows offshore 36% of the time (10 days in an average May). During a typical May wind stronger than >40kph (25mph) was expected for only a single days at Erromardie
