Diggers Wind Stats

The rose diagram describes how commonly and how strongly the wind blows from different directions through a typical April. The largest 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 2880 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Diggers, located 33 km away (21 miles). There are not enough 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 Diggers blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Diggers. 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 April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 10% of the time (3 days each April) and blows offshore 47% of the time (14 days in an average April). In a typical April winds stronger than >40kph (25mph) are expected on 2 days at Diggers
