Lighthouse Wind Stats

The rose diagram illustrates how often and how strongly the wind blows from different directions through a typical October. 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 3471 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Lighthouse, located 37 km away (23 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 most common 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 illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average October, the model suggests that winds are light enough for the sea to be glassy (light blue) about 3% of the time (1 days each October) and blows offshore just 14% of the time (4 days in an average October). In a typical October winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Lighthouse
