Topleca Wind Statistics, All Year averages since 2006
The rose diagram illustrates how frequently and how strongly the wind blows from different directions over a normal year. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue showing the strongest winds. It is based on 22239 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Topleca, located 26 km away (16 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 dominant wind at Topleca blows from the SSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Topleca. By contrast, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical year, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 37% of the time (135 days each year) and blows offshore 51% of the time (182 days in an average year). Over an average year wind stronger than >40kph (25mph) was forecast for only a single days at Topleca
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
