204 Wind Stats

The rose diagram describes how frequently and how strongly the wind blows from different directions over a normal November. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 3347 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to 204, located 33 km away (21 miles). There are not enough recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at 204 blows from the SSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at 204. On the other hand, dominant spokes show 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 37% of the time (11 days each November) and blows offshore 50% of the time (13 days in an average November). Over an average November winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at 204
