This picture illustrates how frequently and how strongly the wind blows from different directions through a typical February. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 3120 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Birsay Bay, located 17 km away (11 miles). There are insufficient 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 prevailing wind at Birsay Bay blows from the WNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Birsay Bay. Converseley, dominant spokes show favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average February, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 4% of the time (1 days each February) and blows offshore just 31% of the time (9 days in an average February). In a typical February winds stronger than >40kph (25mph) are expected on 10 days at Birsay Bay
