The Bluff Wind Stats

The graph shows how often and how strongly the wind blows from different directions through a typical July. The biggest 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 the darkest shade of blue. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to The Bluff, located 43 km away (27 miles). There are insufficient 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 prevailing wind at The Bluff blows from the E. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at The Bluff. On the other hand, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average July, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 6% of the time (2 days each July) and blows offshore 21% of the time (6 days in an average July). During a typical July wind stronger than >40kph (25mph) was predicted for only a single days at The Bluff
