Peggys Wind Stats

The rose diagram illustrates how frequently and how strongly the wind blows from different directions through a typical October. The longest 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 3223 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Peggys, located 12 km away (7 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 Peggys blows from the ENE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Peggys. Converseley, dominant spokes illustrate favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average October, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 3% of the time (1 days each October) and blows offshore just 9% of the time (1 days in an average October). In a typical October winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Peggys
