Nagahama Wind Stats

The figure illustrates how frequently and how strongly the wind blows from different directions over a normal April. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2880 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Nagahama, located 24 km away (15 miles). There are not enough recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Nagahama blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Nagahama. 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 April, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 0.7% of the time (0 days each April) and blows offshore just 3% of the time (0 days in an average April). Over an average April winds stronger than >40kph (25mph) are expected on 3 days at Nagahama
