Gonubie Reef (The Lefts) Wind Stats

The rose diagram describes how often and how strongly the wind blows from different directions through a typical June. 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 the darkest shade of blue. It is based on 3266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Gonubie Reef (The Lefts), located 19 km away (12 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 Gonubie Reef (The Lefts) blows from the S. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Gonubie Reef (The Lefts). On the other hand, dominant spokes represent favoured directions, and the more deep 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). During a typical June winds stronger than >40kph (25mph) are expected on 3 days at Gonubie Reef (The Lefts)
