Rhos-On-Sea Wind Stats

The figure illustrates how frequently and how strongly the wind blows from different directions over a normal April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 3020 NWW3 forecasts of wind since since 2008, at 3hr intervals, for the closest NWW3 model node to Rhos-On-Sea, located 26 km away (16 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 dominant wind at Rhos-On-Sea blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Rhos-On-Sea. On the other hand, 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 (pale blue) about 5% of the time (2 days each April) and blows offshore 13% of the time (0 days in an average April). Over an average April wind stronger than >40kph (25mph) was expected for only a single days at Rhos-On-Sea
