Chirimena Wind Stats

The figure illustrates how frequently and how strongly the wind blows from different directions through a typical April. 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 3360 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Chirimena, located 56 km away (35 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 prevailing wind at Chirimena blows from the NE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Chirimena. On the other hand, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 1.7% of the time (1 days each April) and blows offshore just 3% of the time (1 days in an average April). During a typical April winds exceeding >40kph (25mph) are not expected, but 8 have winds on the range 30-40 (19-25) at Chirimena
