Agate and Pearl Street Wind Statistics, All Year averages since 2006
The rose diagram shows how frequently and how strongly the wind blows from different directions through a typical year. The largest 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 28044 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Agate and Pearl Street, located 21 km away (13 miles). There are too few recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Agate and Pearl Street blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Agate and Pearl Street. By contrast, dominant spokes illustrate 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 (light blue) about 15% of the time (55 days each year) and blows offshore 20% of the time (69 days in an average year). During a typical year wind stronger than >40kph (25mph) was expected for only a single days at Agate and Pearl Street
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.
