Fortress Wind Stats

This image describes how often and how strongly the wind blows from different directions through a typical April. The longest 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 dark blue. It is based on 2880 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Fortress, located 4 km away (2 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 most common wind at Fortress blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Fortress. On the other hand, dominant spokes represent 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 April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 5% of the time (2 days each April) and blows offshore 32% of the time (8 days in an average April). During a typical April winds stronger than >40kph (25mph) are expected on 3 days at Fortress
