Rhosneigr Wind Stats

The graph illustrates how frequently and how strongly the wind blows from different directions through a typical October. 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 showing the strongest winds. It is based on 3471 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Rhosneigr, located 26 km away (16 miles). There are not enough 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 Rhosneigr blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Rhosneigr. Converseley, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average October, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (2 days each October) and blows offshore 16% of the time (2 days in an average October). In a typical October winds stronger than >40kph (25mph) are expected on 2 days at Rhosneigr
