Lighthouse Wind Stats

This picture illustrates how frequently and how strongly the wind blows from different directions through a typical August. 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 deep blue. It is based on 3582 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Lighthouse, located 20 km away (12 miles). There are not enough 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 Lighthouse blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Lighthouse. Converseley, 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 August, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (1 days each August) and blows offshore just 50% of the time (15 days in an average August). In a typical August wind stronger than >40kph (25mph) was forecast for only a single days at Lighthouse
