Grabbers Wind Stats

This picture describes how frequently 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 indicates the strength, with deep blue showing the strongest winds. It is based on 3192 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Grabbers, located 29 km away (18 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 Grabbers blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Grabbers. By contrast, dominant spokes show favoured directions, and the more deep 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 (pale blue) about 10% of the time (3 days each May) and blows offshore 48% of the time (15 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 2 days at Grabbers
