Belharra Wind Stats

The rose diagram describes how often and how strongly the wind blows from different directions through a typical November. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue strongest. It is based on 3347 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Belharra, located 23 km away (14 miles). There are not enough 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 dominant wind at Belharra blows from the WNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Belharra. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average November, the model suggests that winds are light enough for the sea to be glassy (light blue) about 14% of the time (4 days each November) and blows offshore 29% of the time (8 days in an average November). During a typical November winds stronger than >40kph (25mph) are expected on 4 days at Belharra
