Mapuzi Wind Stats

The figure illustrates how often and how strongly the wind blows from different directions through a typical June. The longest 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 3266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Mapuzi, located 30 km away (19 miles). There are not enough 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 dominant wind at Mapuzi blows from the ESE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Mapuzi. Converseley, 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 June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (1 days each June) and blows offshore just 13% of the time (4 days in an average June). During a typical June wind stronger than >40kph (25mph) was expected for only a single days at Mapuzi
