TCs Wind Stats

The figure illustrates how commonly and how strongly the wind blows from different directions over a normal November. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue strongest. It is based on 3347 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to TCs, located 29 km away (18 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 TCs blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at TCs. On the other hand, dominant spokes illustrate favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical November, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 32% of the time (10 days each November) and blows offshore 52% of the time (14 days in an average November). Over an average November winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at TCs
