Belharra Wind Stats

The rose diagram describes how often and how strongly the wind blows from different directions over a normal May. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue strongest. It is based on 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Belharra, located 23 km away (14 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 most common wind at Belharra 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 Belharra. 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 (light blue) about 21% of the time (7 days each May) and blows offshore 33% of the time (10 days in an average May). Over an average May wind stronger than >40kph (25mph) was forecast for only a single days at Belharra
