Topleca Wind Statistics, July averages since 2006
This chart describes how commonly and how strongly the wind blows from different directions through a typical July. The longest 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 strongest. It is based on 2232 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 too few 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 prevailing wind at Topleca blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Topleca. 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. Over an average July, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 38% of the time (12 days each July) and blows offshore 54% of the time (17 days in an average July). In a typical July winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) 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.
