Chuns and Jocks Reefs Wind Stats

This image shows how commonly and how strongly the wind blows from different directions through a typical May. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 3406 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Chuns and Jocks Reefs, located 42 km away (26 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 Chuns and Jocks Reefs blows from the NNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Chuns and Jocks Reefs. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (1 days each May) and blows offshore just 35% of the time (11 days in an average May). In a typical May winds exceeding >40kph (25mph) are not expected, but 3 have winds on the range 30-40 (19-25) at Chuns and Jocks Reefs
