Lighthouse-Southside Wind Stats

This image shows how often and how strongly the wind blows from different directions over a normal June. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 3506 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Lighthouse-Southside, located 40 km away (25 miles). There are not enough recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Lighthouse-Southside blows from the S. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Lighthouse-Southside. By contrast, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical June, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 6% of the time (2 days each June) and blows offshore 19% of the time (5 days in an average June). Over an average June wind stronger than >40kph (25mph) was forecast for only a single days at Lighthouse-Southside
