San Simeon Creek Wind Statistics, All Year averages since 2006
The rose diagram describes how frequently and how strongly the wind blows from different directions through a typical year. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue showing the strongest winds. It is based on 26700 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to San Simeon Creek, located 35 km away (22 miles). There are insufficient 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 San Simeon Creek blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at San Simeon Creek. By contrast, 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 year, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (15 days each year) and blows offshore just 6% of the time (22 days in an average year). During a typical year winds stronger than >40kph (25mph) are expected on 4 days at San Simeon Creek
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
