Middle Rock Wind Stats

The rose diagram shows how often 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 implies the strength, with the darkest shade of blue showing the strongest winds. It is based on 3266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to MiddleRock, located 16 km away (10 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 most common wind at MiddleRock blows from the S. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at MiddleRock. Converseley, 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 June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 11% of the time (3 days each June) and blows offshore 44% of the time (13 days in an average June). In a typical June winds stronger than >40kph (25mph) are expected on 3 days at MiddleRock
