Morfa Mawr Wind Stats

The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue showing the strongest winds. It is based on 2838 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Morfa Mawr, located 16 km away (10 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 prevailing wind at Morfa Mawr blows from the WSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Morfa Mawr. 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. Over an average May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 13% of the time (4 days each May) and blows offshore 28% of the time (0 days in an average May). During a typical May wind stronger than >40kph (25mph) was predicted for only a single days at Morfa Mawr
