Saviskaill Bay Wind Stats

The rose diagram describes how frequently and how strongly the wind blows from different directions over a normal May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 3422 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Saviskaill Bay, located 34 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 dominant wind at Saviskaill Bay blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Saviskaill Bay. On the other hand, 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. During a typical May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 7% of the time (2 days each May) and blows offshore 35% of the time (11 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 3 days at Saviskaill Bay
