(any wind direction)

The rose diagram describes how commonly and how strongly the wind blows from different directions over a normal March. The largest 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 Gas Bay, located 46 km away (29 miles). There are not enough 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 most common wind at Gas Bay blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Gas Bay. By contrast, 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. During a typical March, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (1 days each March) and blows offshore just 51% of the time (16 days in an average March). Over an average March winds stronger than >40kph (25mph) are expected on 5 days at Gas Bay
