Mimiwhangata Wind Stats

The rose diagram shows how often and how strongly the wind blows from different directions over a normal May. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue showing the strongest winds. It is based on 3414 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Mimiwhangata, located 10 km away (6 miles). There are insufficient 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 prevailing wind at Mimiwhangata blows from the N. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Mimiwhangata. Converseley, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 1.2% of the time (0 days each May) and blows offshore just 3% of the time (1 days in an average May). Over an average May wind stronger than >40kph (25mph) was expected for only a single days at Mimiwhangata
