The Delta Wind Stats

The rose diagram illustrates how frequently and how strongly the wind blows from different directions through a typical June. 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 3266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to The Delta, located 47 km away (29 miles). There are not enough 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 The Delta blows from the ENE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at The Delta. On the other hand, 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 June, the model suggests that winds are light enough for the sea to be glassy (light blue) about 0.2% of the time (0 days each June) and blows offshore just 0.5% of the time (0 days in an average June). In a typical June winds exceeding >40kph (25mph) are not expected, but 6 have winds on the range 30-40 (19-25) at The Delta
