(any wind direction)

The rose diagram shows how commonly and how strongly the wind blows from different directions over a normal March. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 3212 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Grandma's, located 33 km away (21 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 Grandma's blows from the SW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Grandma's. 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 March, the model suggests that winds are light enough for the sea to be glassy (light blue) about 7% of the time (2 days each March) and blows offshore 33% of the time (10 days in an average March). Over an average March winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Grandma's
