Morro Rock Wind Stats

This picture illustrates how frequently and how strongly the wind blows from different directions through a typical September. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 2880 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Morro Rock, located 45 km away (28 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 Morro Rock blows from the WNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Morro Rock. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average September, the model suggests that winds are light enough for the sea to be glassy (light blue) about 10% of the time (3 days each September) and blows offshore 10% of the time (3 days in an average September). In a typical September wind stronger than >40kph (25mph) was expected for only a single days at Morro Rock
