Mntafufu Wind Stats

The rose diagram illustrates how frequently and how strongly the wind blows from different directions through a typical July. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 3472 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Mntafufu, located 39 km away (24 miles). There are insufficient 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 Mntafufu blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Mntafufu. On the other hand, dominant spokes represent favoured directions, and the more dark 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 5% of the time (2 days each July) and blows offshore 19% of the time (6 days in an average July). In a typical July wind stronger than >40kph (25mph) was forecast for only a single days at Mntafufu
